Ok. First thing I want to say, is good job, its a fun game and you've obviously put effort into it.
Second thing I want to say, and I'll be blunt; The control scheme sucks !@#$%. Turning with directional keys does not work in top-down games, regardless of what some people may say. Try using the mouse to direct the character and just relegate the left/right keys to strafing. I would also probably cut down on the amount of keys binded, but thats not particularly important.
Apart from that though, and a few minor issues (collision and what not), its fun, good job.
