you did a bit of an icarus with the videos in the background. Flash is not a powerful platform. Rhythm games need to be able to run perfectly. Get rid of the videos so that it runs smoother and it would be a really good rhythm game. atm 2/5
there should be a button to reset a level because sometimes you get stuck, also there should be a better test for whether the player dies than just if the rider goes upside down
