Drum Rhythm Game

A browser-based drum rhythm game. Notes scroll down the screen and you hit the matching drum pad in time — like Rock Band, but it runs entirely in your browser with no server, no dependencies, no install. Just open index.html.

Works with keyboard, Wii Rock Band drums, Xbox/PS Rock Band drums, Guitar Hero drums, or any USB gamepad. Includes a Remap Pads button to configure any controller.
