Great concept and great art (the wonderful googly eyes on the ball)
The only thing I would have to say is that the player movement is iffy, but then again, making physics body players is always painful, I made one before, and with weeks of working on movement (on and off) it still didn't feel good, so making a working one in 48 hours is very good, expsesly with 3D, the only solution would to have the player not be physics, but then it loses the fun :).
