The best way to describe it would be that its puzzle racing game that makes its tracks from your music. You select a song and a character that determines the style of game you want to play, and the game creates a track for you to play along with the song. You have to try it. You can grab the demo on Steam right here. If don't you want to use Steam to try the game out, you can download a standalone demo here.
