A drum you can feel and see
Cliffdrum is a rhythm game with one input. There is no menu of songs: the cliff is the song. The drum keeps a steady four-beat bar, with a deep boom on the first beat and a lighter tom on the others, and everything you do is judged against it.
The beat is shown as well as heard. The closing ring, the pulsing dots, the flash across the rock and the pulse around the screen edge all land on the beat, so you can play on a train with the sound off. The timing is worked out from the exact moment you touch the screen, not from the frame the game was drawing, so a slow frame doesn't make you late.
