I like the idea of the game, I't really fun to play it with someone :)
For the music background, did you try to attach music to the camera?
Making music is my least favorite part of development. I have no idea how to use minor keys, I suck at making leads, and the software I use randomly buffs up notes, so, when I finished I really didn't have the motivation to make music.
oh, that's why i used a free music in my game ;)
