Cool, but having the background of the web page the same color as the field really messed with the controls. You had to be careful not to move your mouse out of the invisible flash box.

Other than that I like how you can turn the gun from semi-auto to full automatic merely by spamming the mouse button. I quit once I reached 1003 points.

Hey, thanks for playing :) im gonna fix that BG color problem in the next update.
Well, you were so close, the game ends at score 1031, but i think i should make it harder and add some more enemy types, so it would be interesting to play it till the end :)

With these types of games, you need to make the 'goal' score much more attainable and start ramping up the difficulty and variety of enemies much sooner.
Also, I'd like to see an auto-fire option as I quite at about 500 points after my mouse finger got tired.

Yeah, I sure gonna do that :)
Well, the whole idea was to make this game kinda long and with no auto-fire, since it makes it more difficult to complete :) This little game Ive made is based on one I had played when i was about 10-12yrs old. In that game you had to kill several thousands of enemies. After Ive completeted that game I couldnt feel my finger, that was a real challenge :D
