"Completely" original top down shooter

I ran out of motivation to work on this more but thought I should at least turn in what I had. It's a fairly generic top down shooter except that your bullets deal more damage the closer you are to the enemies. Survive as long as you can, feel free to post your score in the comments.

Controls:

Left click to shoot, right click to do an extra powerful attack, scrollwheel to change guns, WASD to move.
