Really cool game man!!! But I found a bug! It's possible to go over the screen boundaries without being bounced back. The easiest way that I found to reproduce it is at the begining of the game by keeping the mouse closer to the top corner of the losangle, in the third beat it will over the screen and it's impossible to get it back. Also, I think would be nice to get some inpirations from Guitar Hero series and similar games by having score and combos.
