I know this kind of defeats the purpose, but while I was making some food. I had a thought of a combination of DDR and Audio Surf. Imagine hitting keys RIGHT on the blocks that you need. Giving the game some sort of DDR-esque feeling, if anybody knows what I'm talking about. Okay, so if you're following me, imagine all of the arrows and such riding on a track that you surf on. You hit a certain key right as a block comes by.
Umm...
Maybe there is a game mode that requires you to hit blocks already? ??
