Love the idea, hate the controls
This is a really great idea, but the controls really bugged the hell out of me. Way too easy to just miss something and then have to wait that infuriatingly long time before your ball respawns. Maybe it's just to make it more difficult but to me it just made it frustrating and I didn't want to play a second time.
Also would have been useful to have shortcut keys for the powerups, and I noticed a NaN bug in the score after one level.
Other than that though, cool idea, loved the celebrities and the graphics in general were well done.
