Really awesome arcade shooting game !!!
If you reach higher levels it ends in an strategic fight for keeping a constant upgrade flow to constantly keep the enemies away from you. Also requires fast and highly accurate mouse movements.
This game keeps my attention from time to time since its release now for ~1,5 years
But... Your highscore-upload-function doesn't work always.
Made it from lvl 63 to 67 in one run, had to pause the game for a few hours in between and made 7,8mio points. Pressed uploiad, but it didn't show in the highscore list...
