Wow, just wow. I've played many clicker games in my life, but this, this is just pure genius. Spaceplan is unlike anything I've ever played in my life. Everything about it hooked me instantly, from soundtrack to gameplay to mood to colors to story. So if you love space, clicker games, and a phenomenal soundtrack, Spaceplan is specifically for youShow moreShow less

In the idle clicker spectrum of 'heavy management' to 'completely idle', SPACEPLAN is much closer to the latter; there isn't a ton to do other than sit around and wait. There also isn't a lot to look at. The minimalist graphics are nice, albeit... Well... Very minimal. The UI is nice in a functional kind of way, but again, nothing groundbreaking. The humor is cute. I like my idle clickers to have a bit more meat-on-the-bone, with some choices and management. If you are looking for a great modern clicker, check out Idle Evolution instead. Again, I don't think SPACEPLAN is horrible per-se, there just isn't enough to it as far as what you are doing at any given point in time. It's less about spending the money with this game than it is about spending your precious gaming time. Finally, SPACEPLAN uses the top right of the store page to state exactly one sentence to describe the game that includes a comparison to Stephen Hawking's book A Brief History of Time. OK great, I love that title. I love idle clickers.A match made in heaven - I am sold. Too bad I can't see any of that book in this game. The dev did respond to a forum post I had with this conundrum, but I'm still left a bit underwhelmed at the abstract connections (and yes, it is an abstract book lol). I just think its fair warning to anyone whose interested was piqued from that first sentence. SPACEPLAN is not the worst idle clicker, but I did not find it engaging enough to recommend my friends go out and spend money on it.Show moreShow less

An out of this world clicker that serves up a Sci-fi narrative, Spaceplan give us a computerized space age sim with fully automated potential. Is it a Rocket? Is it a Science Fair Project gone awry? No, it’s a potato-driven effort at time travel. A totally unscientific look at the Science behind shooting potatoes into the sun, Spaceplan has you clicking a button to launch spudniks into orbit. With a clean, humorous interface, with self-effacing generic titles, the narrative becomes the focus of the game. As you add to your potato arsenal from the items on the left, and upgrade with research ideas on the right, more spud power is generated to propel your starchy voyage to return a dead earth to its former glory. What I liked most about Spaceplan was that it left out the drag of hand-numbing clicking. There are no set number of clicks required to complete the game. And, the ability to upgrade means that the power continues to generate even while you have the game closed. Clicking speeds up the generation rate. Of course, macros work here too if you really want to speed things up. So, you are totally in control of the narrative. Most importantly, it is a clicker that you really can’t stop playing until the end… or is there an end? The story is circular, and could keep going. So, theoretically you could keep playing forever. Seriously though, I see absolutely no replay value once you’ve reached the beautiful ending. That ending is fantastic enough to make you close the game with a happy feeling until you realize there is not another clicker like it to fill the new black hole you’ve created. I highly recommend this pseudo-science clicker for all fans of the genre… and for the rest of us who’ve never clicked before.Show moreShow less

Spaceplan is a clicker game. Meaning you click on something, get money, use that money to buy something and then click the first thing again. Repeat 100000000000x times. Spaceplan adds a story, but in 30 Minutes of game time, that's all I'm willing to state. Everyone talks about the clever writing, and yes, I giggled at the options menu and liked the trailer up there but ingame you 1. dont have that much writing, maybe one sentence every couple of minutes and 2. it's not consistently funny. It's the "school of funny" which believes that randomly placing potatoes or replacing random things with potato ('cause we're so random) is enough of a joke to be made 100 times. (Starships powered by potato?! That's not how you power a starship! LOL,ROFL,GG) In Contrast to some other (free...) clicker games like Adventure Capitalist, the game seems shallow, (for a clicker!). In the time I was playing, I could only buy 2 "Moneymaking" things, and about 2 Upgrades for each. Also, you buy probes (sry "Probetato", cause were random, remember?), which are the games way of making you advance the story, though it failed to advance for me even at first because the first 4 (!) probes burn down (maybe more, wouldnt know I stopped). 20 Minutes of burning down probes and telling you to try again seems a bit much for a game that doesnt expect you to pay for superfunbucks to advance quicker. I like the sleek presenation and the nice, though very simple music, but it still makes me wonder why this game costs money when theres literally HUNDREDS of these games for free on the internet.Show moreShow less

This has basically no impact on the game, but it's a thing that annoyed me, so I thought I'd share. Using watts as a unit you amass, like you do in this game, makes no sense. Watts means joules per second, meaning it's an amount of energy (joules) per second. The way the unit is handeled in this game, where you recieve an amount of watts per hour would mean that you have a constant acceleration of energy production (J/s^2). The correct thing would be to name the unit you amass joules, and the energy per second watts. All that being said, I love the game ^^Show moreShow less

I cant honestly recommend this. The story is brilliantly wacks, the soundtrack is magnificent, the visuals are really cool - but the problem with all of it (at least for me, ymmv) is that it's wrapped in an incremental/clicker game that just... isnt incremental. You very quickly get to a point where you cant really unlock anything new, your upgrades barely matter (x2 earnings from one thing, as a "lategame" upgrade in a game like this? come on...), and you're just left with tedium to see what's next. Or straight up frustration, once you get a bit into the second part of the game. Now, do I regret spending the few quid on this? No, it's a cool enough idea that I dont mind tossing that over to the dev in appreciation - but I also wouldn't do it again... does that make any sense? No idea, but there you go :)Show moreShow less

Do you remember No Man Sky promising so much and delivering so little? do you remeber they said we would get something amazing at the end of the game? Yes, Spaceplan does the oposite, it promisses very little, but it does deliver something truly great at the end of it. 11/10 Amazing, just that, amazing.Show moreShow less

Con: * Total play TIme for me was 7h. * I nearly missed the stephen hawking stuff that the description promised. it's basically mentioned once or twice but the game could've worked without mentioning him. i feel mislead. * no replay value. the progression is linear. You're not invited to try different play styles. Pro: The narrative and soundtrack were a nice touch.Show moreShow less

Minor spoilers This idle game is about the narrative, not about the mechanics. It presents a grand mystery: you awake as the sole human operator of a highly advanced spacecraft, in orbit above a far-future Earth mysteriously devoid of all life. Your ship AI makes a plan to travel back to the big bang, ensure that time progresses identically to how it did in the previous universe's incarnation, so that you can observe the Earth and see what happens to cause the end of human civilization, with the goal of preventing it. Upon arrival, however, you learn that the Solar system has been entirely reengineered by some unknown power. The planets have been redesigned in their entirety into giant planet-shaped machines with some unknown purpose which you must unlock. Your AI has some kind of theory as to what's going on. Basically, the mystery narrative that the game presents the player reminds me of the TV show Lost. Some mysterious, unseen great power bending events surrounding the protagonists towards a particular end, the feeling when that which was safely regarded as natural is revealed to be artificial, etc. It's mystery porn of the highest order. Unfortunately, just like with Lost, there is no satisfactory explanation for these mysteries. Even though the game pretty explicitly claims that your AI has a strong theory, and just wants to wait for further confirmation before telling you... the revelation simply never occurs. The mystery is left totally unsolved by the time end credits roll. And that makes me *furious* at the developer. Never have I felt so blueballed. It's about as disappointing as the series finale of Lost. If you can't stand that kind of thing, like me, then I would advise not playing this game. If you don't really care about the fact that the narrative is unfulfilling, then honestly this game is probably not for you, since the gameplay mechanics are simple and there are better idle games out there. Having ruled out those two kinds of people... I'm not sure exactly who is left. Maybe no one.Show moreShow less
