Great music, sound, and glass shatter physics! Movement felt very solid and responsive too. I also love what appeared to be an online leaderboard, which is a nice touch.
Changes I'd make is to have music persist through reloads, make it so you can't jump high enough to get rid of the bottom platforms (causes a huge graphical issue when the bloom cuts out), possibly add in running and death splat sounds, and I'd try and make the menus controller friendly.
Fun game!
