Great job, it was fairy simple and fun to play. I liked the camera shake, it really made it feel like the bullets had recoil. The boxes were some times difficult to move and if you were against a wall at all it seemed like you couldn't move much at all. Also, I assumed that the distance your mouse was from the character would change how much recoil your gun had but it didn't seem to. I would recommend something like that though instead of using space to brake, I think it feels a bit more natural with a game like this.
