I made a small demo to test using your phone's motion sensors as a game controller

No gamepad, no extra hardware. One device runs the game (PC or Android) and every phone on the same Wi-Fi becomes a motion controller. Some modes also use the phone's vibration for feedback, so you feel the hits and the road. The most fun modes right now are ping pong (vs AI or 1v1) and racing. I also tried baseball and boxing, but in my opinion they didn't turn out fun enough. It's built in Godot with Claude Opus 5.5 driving the editor through an MCP server: writing the code, setting up scenes and running playtests. The 3D models were also generated by Claude, using Blender through its MCP.

I'd love to hear how the controls feel!
