The concept of this game is very funny, and with some polish t o the controls (Like others have mentioned), and a bit for work on the art, this could a smash hit!
Personally, I would recommend switching to 2D graphics, as there isn't really any necessity to use 3D for this game to work, and it would be easier to make.
