Over the christmas days I created Motion Party, a webcam motion controlled game inspired by Eyetoy and the Nex Playground. Currently there are 8 games for between 1 and 4 players, including a ball game, a game similar to flappy bird, a memory game and a spelling game.
I made it mostly using Claude Code, and Eleven labs for sound effects. The graphics are rendered in p5.js. It should work on mobile as well as desktop, you just need a camera.
I think they're really fun, especially with more players playing together. My grandmother was able to play as well, which was cool to see. Let me know what you think, and merry christmas! :)
