Not bad
Im on level 7 and at this point im just blowing the shit out of everything. Bosses are to easy and im also hearing ads pop up in the backround lol. Also if you limited the number of noises going off in the game it would be less annoying to hear the computer voice repeat itself several times in a row. I like watching the pixels explode from my massive guns, the pixel animation is the best part of the game. All in all its pretty fun.
