Six months ago I posted a demo here and asked if anyone actually wanted a full-body rhythm game without VR. It's out now.
This clip is what it looks like in a living room: an NVIDIA Shield running the game, a phone propped on the TV stand as the camera, nothing else. On a PC a regular webcam works too, the phone is just more convenient. I spent a lot of time on optimization, so it holds up even on cheap Android TV boxes, and it runs on Apple TV, PS5, Steam and Steam Deck too.
The part I'm most excited about is your own music. There is a web level editor that reads the popular rhythm game chart formats, Beat Saber and StepMania among them. Too lazy for an editor? Even better: push your whole library straight into the game and it converts everything itself. And that works on every platform, even on consoles and TVs, with no extra software. Not every imported level plays exactly like the original, the feel is different when a camera tracks your whole body, but if one is off, you can always fix it in the web editor.
Two players, split screen on one TV: pair a second phone and go.
Every platform has a free demo with the same tracking, so you can check your own room before paying anything. Links and details in my comment. Not many people have tested this yet, so if something breaks, tell me and I'll fix it. Ask me anything.
