Interesting idea, I just wish you had run with it a bit more. Sucking dudes into a black hole is pretty satisfying, but when I learned you couldn't do it to the cars, buildings, trees, I was pretty disappointed. Also the camera, which I know other comments have already spoken about but it is such an issue to not be able to turn around completely.
The music kicked butt, but it really didn't match with the pretty meager amount of enemies that you throw at the player. The scenery was nice, though the lighting could use a little bit of work.
Overall not a bad attempt!
