Nice game
The graphics are good and the game concept is fine, but there were a few things that bothered me.
1) You die way too fast. Some people like the challenge, but seeing that you can't dodge and shoot at the same time, I kept dieing whenever I pulled my gun.
2) Controls... are you left-handed? Might have something to do with the fact that I'm on a laptop, but both my hands are on the far left of the keyboard and that's horrible. You could make the arrow keys and W-A-S-D keys do the same thing so people can choose.
For the rest it looked nice, though I didn't get very far...
