Overall this is a fun concept, and everything fit together nicely, but collision detection and fire detection were very poor. Every play if you got close to the edge you were forced out of bounds, and then you couldn't get back in. Also, the enemies would freeze against an invisible wall taking all the fun out of killing them. No challenge at that point. I think this could be a great game if those things were fixed, a larger level made, and if the enemies did something different than just follow you around and smother you to death...
