I like the "you are your own worst enemy" mechanic, and it flows surprisingly well with Pac-Man style gameplay.
Overall I'd say the game is solid gameplay-wise.
Music is bad. I recommend looking up some tutorials on music theory. Those'll help out on future compositions. Or even just use some of Newgrounds' music. There are plenty of people offering their music for free to game makers on Newgrounds.
Also the art here is rather boring, it's all different sized parallelograms. I know graphics aren't everything, but believe me when I say that people love a good looking game. Stylized graphics aren't very difficult to pull off (I guess different sized parallelograms is a style. It just isn't a very nice one).
I wish you luck on your next venture.
