I wish the robots were more realistic, cuz when they come out their holes they look like little dwarfs instead of killer robots. Also, if I were you I'd try to improve the guns, the guns are waaaayyy to overpowered... I take i hit and i already have half hp gone!!!
And please add a little pink elephant~ 1/5
why don't i get badges or highscore? i played through all the 15 lvls killed more then 10 evil UFO's and split 5 with a single shot, and my highscore won't save either :S 4/5
