Controls need some work . . .
I can see this being a pretty fun game, there are just a few things you need to adjust, one being the speed at which the face moves after it gets hit around. It is much too quick, you might also want to explain the faint line showing you where your paddle can go, or at least have the line more visible. It took me a little while to understand that there was a line there and what it does.
Other than those couple problems the game is good, the art is done very nicely, and the idea is sound (even if the patients aren't, hahaha I am a comedian). The sound effects also go nicely with the game.
