TL;DR OPUS: Echo of Starsong is among the best releases this year. Its story combined with stunning visuals and gorgeous music will most certainly melt your heart and make you cry. It also provides a serviceable resource management game loop to keep you engaged while visiting each location and exploring lore of the world. Here are some extra points: Visuals Actually, not much to add. Look at the screenshots and all I can tell you is that the game just looks that great. Music Those piano notes are absolute masterpiece. The main theme just gives me chills whenever it hits. Gameplay The main game loop revolves around managing your fuel while travelling between space stations and asteroids. Though there are random events and skill checks at play, the game is pretty forgiving in this regard. This is no FTL. Some puzzles are involved while exploring locations, but they are never hard enough to pose any challenge. I’d say the mechanics are mostly there to keep you actively engaged without the game turning into full blown walking simulator or visual novel. Story OPUS: Echo of Starsong is a story told through a series of flashbacks. As you travel in the world, you’ll delve more into the history of each character and the world itself. I’d rather not spoiler main story beats so let me tell you this much: The game tries very hard to immerse you into its world. Every descriptive text is another lore shown, much like how From Software’s works were done. (Pretty crazing comparing these two, huh?) And I’d say they’ve done an astonishingly good work in building an unusually designed universe. The best I can describe it is an oriental flavored Star Wars which doesn’t lean much into hardcore sci-fi, and its uniqueness intrigues me to explore more of it at all times during my gameplay. Technical Issue All above that make the game great are fortunately not overshadowed by its technical issue. I’ve encountered a game breaking issue midway during my initial playthrough, but the devs quickly responded and worked with me in identifying the problem. Since then the bug has been fixed with a progression hard lock so I have updated my review to reflect this change. Here are some extra hiccups to note though: The game runs at a weird 36fps (probably due to me using a 144Hz monitor) on my extremely powerful machine. Thankfully the gameplay doesn’t particularly demand high framerate, but it is indeed jarring. There are no anti-aliasing available for some reason, which is a shame for screen capturing this otherwise beautiful piece. No option to go 4K, currently capped at 1440p which also worsens graphics a bit if you are running on a 4K display. All in all, a solid 10/10 for those who love atmospheric adventure game, story heavy exploration game, and maybe just whoever enjoys soothing visuals and music.Show moreShow less

It somewhat pains me to rate this negatively because there are a lot of things I did like. The art style is beautiful, the puzzles are nice, the soundtrack is good, and the gameplay, while simple, is quite engaging. But a game like this lives and dies by its story, and while the setting is original, the characters are so paper thin and poorly characterized that the story as a whole falls flat. Character A hates Character B, which is mostly conveyed through A saying 'I hate B!' for at least 3/4 of the story, until that arc less resolves than is just forgotten. Character B immediately abandons their original quest 10% of the way into the game to follow Character C for the repeatedly stated and paper-thin reason that these people they just met 'are my family now!' This original quest is repeatedly reintroduced as a means to increase tension - will they leave? Will they stay? - but always by some other character, usually A frantically telling C that B's departure MUST be imminent. But Character B never worries. They are staying because "You are my family now!" which is, more or less, their only motivation for the remainder of the game. Character C is trying to find Character D, who in flashbacks repeatedly tells Character C to be their own person and go off on their own adventures, but, as you may now see is a repeating theme - Character C does not deviate for a moment. Character C proceeds to make dumb mistake after dumb mistake on their quest, with those rash decisions being the overwhelming driver of the plot. In a better plot, we'd have character growth. C would learn to let D go. B would actually struggle to decide between actual and found family. A would recognize their feelings towards B as coming from a place of fear as to what B would do to the relationship forged between A and C. But no, none of that happens. B abandons their family until the game is over, A hates B until it is just forgotten and C continues to try to find D to catastrophic effect. And its too bad, because, behind it there is a really neat mythology and hidden backstory to some of the characters that I kept hoping would get woven into the main plot at some point - lost heirs, prophesied reincarnations of gods... I kept pushing aside my annoyance with the plot, confident that this really cool stuff would eventually show up in later acts... but they don't. By the end of the game I was left just deeply dissatisfied by the whole experience.Show moreShow less

”The Galaxy is Vast and Yet Fate Brings Us Together.” I’ve to admit that I never play previous title of OPUS series. Visual and soundtrack from preview are first two things that grab my attention and decide to give it a try. After the credits roll, it’s hard to describe this sleeping hit in few words, but I’m really glad to experience and cover this gem. OPUS: Echo of Starsong (EoS) is linear story-driven adventure game developed by Taiwanese team SIGONO. This subjective review is written based on version 1.4.3 which might address most previous issues. Our Name Was Known Across the Stars EoS storytelling is strongest part and best to experience blindly from the beginning as I want to minimize the context in story section. The OPUS series shares the same universe, but each story is standalone and completion. The aftermath of galactic war caused by factions to claim ancient power of Lumen civilization, the journey of a man who intent to bring honor back to his clan by claiming Lumen cave under his name, and wandering young girl who can sense Lumen asteroids by imitating Starsongs. This is story of fate and destiny of two people echoing across solar system named Thousand Peaks. https://steamcommunity.com/sharedfiles/filedetails/?id=2666856624 Eos is an emotional narrative of space journey and memorable casts driven by strong motive and personality. Most are mainly represented in text-based form with visual background. Various events and screenplay gives fair time to slowly build character development even the pacing is sometimes quite fast and shifts between flashback and present. You might expect foreshadowing from the prologue, but the story still has element of surprise and mysterious. It also centers on character relationship which feels much more personal and emotionally attached from the beginning to the end. Thousand Peaks is also full of different kind of people suffered or traumatized by war and mysterious of Lumen civilization. The Myrian mythology of Lumen set an interesting and complex world background that well integrates and deeply connects to the main story. Amount of information and poetry form might be overwhelming and require time to invest. Once it clicks and comes together, it genuinely feels rewarding and positively satisfying to be that way. The contrast between fantasy and sci-fi element and writing that carefully craft and merge together. The ideology of afterlife, consciousness, morality, responsibility, and life lesson are some parts I learn and appreciate from the playing the game. Those elements simply create one of most beautiful and memorable story I’ve experienced in indie title so far. The Arts of Thousand Peaks Indie games usually take art direction in compensate for graphic quality. The game assets are simplistic and low-poly blocky artstyle, but surprisingly amazed by their complexity when it comes to Myrian architecture and spacecraft / station aesthetic that represent background history and culture of Thousand Peaks' habitants. Beautiful hand-drawn 2D illustration and composition create strong character expression and easy to follow from heartwarming to intense moment. Big props to artist and 3D team! Together with Red Chamber EoS is a game of journey with combination of side-scrolling adventure, puzzle, and space expedition. The game shifts between different gameplay in order to refresh the change of pace and diversity. Side-scrolling section usually triggers in main story progression as player takes control of main characters and either interact environment or solve the puzzle to progress through story. https://steamcommunity.com/sharedfiles/filedetails/?id=2666863754 Most of puzzles are tuning different Starsongs to match the pattern or interact in correct sequence. Some might require clue, but they are pretty straightforward and very forgiving. It might lack challenge in exchange for casual friendly and fitting focused narrative. Space expedition also plays a big part in EoS. Player can explore various optional places (space station, Lumen cave, and planet) to scavenge resource or gather piece of information (memories) to learn more about Thousand Peaks. However, every action costs your resource (for example: amount of fuel consumed by distance or use exploration kit for random resources). Moreover, player also encounters various events when approaching new location ranging from small decisions to roll-dice event that may cause harm to your ship. The key is to plan your route and always trade sellable items for money to repeat and expand the new area. https://steamcommunity.com/sharedfiles/filedetails/?id=2666868126 The expedition emphasizes on preparation and resource management. It gives a strong sense of unpredictable space journey under inspiration of tabletop adventure and representation of Lumen War aftermath. A Rough Journey Tabletop RNG element might offer an unpredictable experience in first playthrough, but it could be frustrating and create unnecessary extra layer of resource grinding or disrupt the flow of storytelling. The problem is most memory collectables are tied to specific choice (or success dice roll) in every event. The dialogue choice doesn’t completely change or impact the story other than slightly different set of conversation and achievement, making one choice is always superior to the other. The lore information you read and interpret from memories help to fulfill the whole picture of the story and I personally think it shouldn’t be messed by uncontrolled RNG event (some items can enhance luck, but worst case still happens) and choice could at least affect fate of side characters. The single-slot auto save system also means action can’t be reversed and easily to mess up. As a linear story-driven game, I could understand the purpose of creating different experience for some players, but look into some designs; it feels self-contradictory and way more punishing especially for completionist and perfect run achievement. Audio / Soundtrack Each track in EoS are beautifully and well composed by Triodust. It has variation genre which fit each scenario or main location player are visit; sense and feeling of adventure, departure, pushing, and hope along the journey. The vocal part voiced by Cikado is also beautiful haunting especially Starsongs that the artist imitates and reflects one of main protagonist inner thoughts. Once the story and visual set up the direction, the music will do its part and exceed my expectation to emotional level. Performance / Technical Aspect EoS is powered by Unity Engine (2019.4.3). The game runs smoothly with solid performance (Win 7, GTX 1050 Ti, 8GB RAM, 1080p resolution). Display type and resolution are only graphical option and the game doesn’t have key binding feature, but it’s doable due to its simple control scheme and friendly UI design. The game lengths between 7-10 hours on first playthrough depended on your pacing / reading and offers chapter replayablity for100% collectable. The game is functional and I haven’t encountered any game breaking bugs or crash so far. Closing EoS holds a very special place in my heart despite some gameplay flaws (at least in my perspective). It deserves more attention and potentially can be a solid animation. If you’re looking for a touching relationship and story rich world with light element of gameplay gimmicks, Echo of Starsong is one of absolute choice of experience that might emotionally inspire you and many more.

Originally, I was actually going to leave a positive review listing the aspects I liked but with a big warning about the ending. But before that, to leave a fairer review I wanted to replay a chapter or two, read the in-game chapter synopses/lore, and watch the "Behind the Scenes" unlocked for beating the game. It has now been a few months but I have had zero desire to replay the game; if not for the voice-acting update I wouldn't have even opened the game in that time. When I first finished the game, I thought the ending was bad. With a few months of reflection, I can now say that I was wrong; the ending isn't bad, it's one of the worst I've ever experienced; I've never had a ending so completely invalidate the time I invested into a story. In many ways this game reminds me of Darling in the FranXX. The plot and characters are nothing special, but the worldbuilding is captivating; the designs of costumes, form of technologies, geography of the setting, and other details all combine to lure you in. Then in DitF, the entirety of Episode 19 is a narrator giving a large, steaming dump of exposition systematically killing all sense of mystery. OPUS also adopts a text dump, but not wanting to be outdone, it doesn't kill just suspense by dumping its lore like DitF: it kills its entire narrative by dumping its ending. Really I can sit here picking apart every aspect of the ending, it's like it was carefully constructed to check off every possible don'ts as a strawman example in a writing textbook. While I might do so later as an exercise, for now I'd rather direct people to some good satire on YT about writing endings. "All you need to do is cross the finish line, and not face plant at the end. ... Readers are more likely to remember the botched ending than the well-run marathon" -Terrible Writing AdviceShow moreShow less

This is my first OPUS game I think. If you like heart touching sad stories this is for you. I do not like stories that just gets super depressing at the end. Thus I do not like this story. But I can see why people would like it. Edit: The worldbuilding, exploration aspects, and visuals are amazing. If you're here for that you probably will not be dissapointed.Show moreShow less

OPUS: Echo of Starsong One of the best narrative driven stories I have encountered in an indie title. The music and sound effects are beyond immersive, elevating the story whilst providing a captivating and enchanting experience. Visit SaveOrQuit.com for daily reviews and here for an easier to read review of OPUS OPUS: Echo of Starsong is an atmospheric narrative driven adventure. It resembles a visual novel in style and has elements of exploration and puzzles. In a distant solar system known as Thousand Peaks, a discovery was made that turned the region into a veritable war zone. Uncovering the ruins of an ancient Lumen civilization attracted many different factions desperate to control the supply of Lumen. The conflict lasted twenty years, known as The Lumen War. The galactic mega corporation, United Mining claimed victory and declared peace in the region. However, the lure of Lumen was too strong and smaller conflicts raged on resulting in the resource being made public. A race ensued to harvest the Lumen. The story revolves around Jun, a Lumen hunter desperate to restore his name, and Eda, a witch, who is searching for her former master. Gameplay Video https://youtu.be/Oz3g6AVtWxk 🤔Overall Impressions🤔 What an incredible game. This is the reason I love indie gaming so much. Every now and again you discover a true masterpiece, and this is one. Everything about the game personifies quality; The story is memorable, touching and emotional; the characters are well developed and cleverly woven into story plots; the visuals are impressive and the sound design is absolutely amazing. It really does have the whole package. This game will appeal to a wide audience although it will mostly attract visual novel and adventure fans. Personally, I don’t tend to like visual novels but you will find heavy influences embedded in the game. Character interactions evolve through dialogue text yet you never feel overwhelmed by content. Conversations bounce between cast members like a game of tennis, rarely stopping long enough to bore or annoy. Discussions are punchy and short yet manage to retain meaningfulness and cleverly build layers on character’s personalities and relationships. The story is incredibly emotional, thanks in part to the wonderful script and character development, but elevated and augmented by the stunning soundtrack and special effects. It is amazing in places and creates such tension and drama that it has you engrossed in events. The story of Eda is based around sound but it gathers new meanings as you progress through the adventure. I thought the story dipped a little in the middle due to the amount of space travel you have to perform. The places you visit can feel a little aimless sometimes yet fans of lore will absolutely love it. The background of the war, the different factions and how Lumen affected the solar system is all explained in detail and provides a thick blanket of knowledge. The presentation of the story is sublime. It is obvious that a lot of time went into developing and executing the story. It goes in so many different directions and is constantly being built up. Events are depicted in a variety of different ways to keep things fresh including flashbacks and dialogue exchanges to exploration and discovery. There are numerous opportunities to stretch your legs and search different locales including Lumen caves and space stations. The caves are relatively linear, but there is scope to explore and collect items to sell for profit, in exchange for maintaining and upgrading your ship; There are light puzzle elements involving opening star gates and Lumen related tasks; There are a few action sequences about and some emotional cut scenes; There are dialogue choices which affect story, relationships, ship and crew. The game is full of variety. Travelling around the solar system can be a little daunting to begin with. You need to manage your fuel levels, shields, exploratory packs and money, and sometimes it is difficult to know which places you have visited before. The story tends to push you in a certain direction, so if you want to explore, do it whilst you can, as you won’t have the opportunity to return after the game has finished. I found this a little annoying as I wanted to mop up some achievements but was unable to. Overall, it is one of the best indie titles I have played and I am sure it will earn many accolades. 🕹️Gameplay🕹️ Gameplay consists of Exploration, Ship management, light puzzle elements and dialogue choices. https://steamcommunity.com/sharedfiles/filedetails/?id=2591932938 Exploration You can explore the area of Thousand Peaks in your space ship, landing at various ports or asteroids. A map of the area is displayed and you can visit any destination visible if you have enough fuel and the scanner is within range. During the journey you can sometimes explore debris using your exploratory packs. These might unearth some goodies for you to use or sell. Each destination will have characters to interact with depending on the type of place you visit. You may have decisions to make which can affect story plots, future relationships or just determine whether you get out of a certain situation without harm. These places can provide a welcome trading post for you to sell or buy much needed items to replenish or upgrade your ship. In some sectors there are starsongs which Eda can detect and sing. Once recorded she can ask Jun to visit its origin and explore the caves it is harbored in. Ship management Managing the ship you will need fuel, protective panels, exploratory kits and money. Each time you travel to a destination you use fuel; If you encounter enemies or asteroid fields your ship might get damaged and use up panels; Exploratory kits are needed to detect items and cash is needed to buy certain items including replenishing the above items. Dialogue Choices There are numerous occasions where you need to decide on an answer. Sometimes these are straight choices affecting plots and relationships whilst others are more luck orientated. Throwing dice will determine the outcome but your chances can be increased by finding certain items with luck enhancers. https://steamcommunity.com/sharedfiles/filedetails/?id=2596191640 Puzzle elements Eda must complete a small puzzle to resonate her starsong correctly by listening to the song and centering parts of the song until it sounds correct. Jun needs to complete an alignment puzzle to open star gates, explore the caves to find the starsongs, and activate lumium pipes. The puzzle elements can be seen in the gameplay video. 📺 Graphics 📺 Visuals are excellent. I didn’t particularly like the over-the-top expressions the characters made during conversations though. I know it is a staple of visual novels but it just seemed out of place. I took far too many screenshots. That just about says it all. 🎵Sound 🎵 Absolutely amazing. Whilst editing my gameplay video I noticed all the wonderful sound effects and background noises you don’t necessarily notice when playing. Headphones are a must to fully appreciate the sounds on offer. The story revolves around sound and it is a central element in everything OPUS does well. 🍳 Conclusion🍳 OPUS: Echo of Starsong is a superior narrative adventure and I would argue one of the best in the genre. There is much variety in the gameplay but generally it is quite slow and dialogue heavy so it will appeal to narrative adventure fans and visual novel enthusiasts. If you like a good story full of drama, twists and excellent character development then I sincerely recommend you give this a go. It is excellent value at full price.Show moreShow less

Run, evade, or rely on luck and plot armor to avoid all dangers on your way as you help a trio of emotional adolescents with a grossly exaggerated sense of duty navigate a solar system on a very specific path in this Chinese-made myth- and symbolism-filled romantic tale with minimal development and resolution to actual romance. You are also extremely unlikely to get all collectibles ("memories") because some of them require luck, and you only get one dice roll without replaying the game — notice how only 0.3% of the players have the "Acquire all items" achievement despite 31.3% (at the time of writing) having finished the game.Show moreShow less

I don't usually leave negative reviews, but at the time of writing this, this game has an overwhelmingly positive rating and that might affect the decision of potential buyers in purchasing it. Let's start with the good. The art style is sleek, with occasional gorgeous cosmic backgrounds that make you pause to take an screenshot or to admire the view. The lore of ancient civilisations and the histories found across the galaxy are quite engaging. The music is pleasant. The gameplay isn't anything revolutionary, but it keeps things flowing and in a visual novel, what carries most of the weight is the story. Now. The story should be taken as a cautionary tale of how not to live your lives. Here we have three characters with extreme fear of rejection having unhealthy relationships. These fears and the refusal to grow and move on often lead to catastrophic decisions and the death of others. It wouldn't be a problem if this was simply a tragic tale offering the perspective of people dealing with many anxieties, but the game goes to great lengths to portray this as beautiful, honourable even. There are also some side plots and conspiracies which are brought up halfway in the game that are never later addressed, but the harmful dynamic of the three main characters are my reason for giving this a thumbs down.Show moreShow less
