Truck sim-style driving game Bunny Garden 2 is heading to crowdfunding

---

Rotary Mouse is a new peripheral from an engineer-entrepreneur working independently, and it is set to launch on Kickstarter on June 17. Its pitch is simple but unusual: remove the traditional mouse wheel and replace it with a built-in rotating wheel; turn it clockwise or counterclockwise to scroll up or down. According to the crowdfunding page, it can even double as a mini steering wheel in slower-paced driving games like Euro Truck Simulator 2.

The real question is whether this solves a genuine problem or just disrupts an interaction people already understand. A standard scroll wheel works, but long documents, large spreadsheets, and timeline-heavy workflows all expose its limits. Repeated flicks work, but they are not especially efficient. That is also where the developer makes the product's main claim: when browsing large documents, the rotating wheel can improve scrolling speed by about 2.5x over a conventional design while reducing the finger fatigue caused by constant finger movement.

The more convincing part is that it does not try to reinvent the rest of the mouse. Rotary Mouse still follows standard vertical scrolling logic, so the learning curve should be far lower than picking up an entirely new control scheme. It also adds haptic feedback and stepped click sensations to help users stop more precisely at the intended point. At least on paper, the design gets the basic trade-off right: speed matters only if accuracy keeps up.

More practically, the key question is who this is actually for. Rotary Mouse is positioned as an office and productivity device. It uses a standard optical sensor with 1600 DPI, measures 119×60×40 mm, weighs about 59 g without the battery, and uses a wireless design. Those specs are clearly not aimed at competitive play. If you want a mouse for FPS games, this is the wrong product category. If your day is spent moving between documents, web pages, and spreadsheets, though, a tool built specifically around scroll efficiency starts to make practical sense.

The catch is the same one every experimental input device faces: the cost of adapting to it, and the actual price. The expected retail price is $139, which puts it well beyond impulse-buy territory. You need to know exactly how much of your day is spent scrolling, and whether improving that part of your workflow is worth paying for. For lighter office use, the traditional wheel may be inelegant, but it remains dependable. For heavier productivity users, especially people working in editing, code review, or long PDF-heavy workflows, a device that specifically optimizes scrolling may offer clearer long-term value.

As for the Euro Truck Simulator 2 mini steering wheel angle, that reads more like a fun bonus than a real reason to buy one. Slower driving games do leave room for unusual peripherals, and this rotary input does resemble continuous steering more than a normal wheel scroll does. Still, it is not a controller purpose-built for driving sims. The takeaway is straightforward: if you are a heavy document user, wait for the June 17 Kickstarter page details and hands-on feedback before deciding. If you are mainly here for novelty in games, $139 is probably paying for novelty more than long-term value.
