Interesting game.  I would have liked it better if it had some sound, at least for the effects. Also some kind of feedback when you get hurt. It becomes hard to know when you're about to die unless you're paying close attention to the health meter. That aside I really liked the pixel-art design of the character and the enemies. 

Interesting mechanics but it got quite hard on the 2nd level. Some kind of healing or more health to start with would be great. It's a pity there are no sound effect and music. Overall a great submission tho, I like it a lot! :)

Nice idea with the gun going off on it's own. It could make for some funny situations. Some music or sound effects would have helped give the game more of an atmosphere. With a little more work I'm sure this could been a really fun game. 

My only critique... I'm more of an average [and right handed] user (just joined to try out a friend's game) and I did not have the coordination to properly play without the use of the arrow keys. Your levels looked nice, and I was a fan of your bad guys!

looks nice, could've used some banger music
