ok i guess...
Stopped at the end of wave 20, since tbh it's one of those endurance games with no ending. If your computer doesn't lag like crazy by this point newgrounders I recommend it as a good place to consider it as completing the game, because once you have a group of the best guns you're pretty much untouchable (move the mouse cursor around the planet shooting and you'll see what I mean). Can't fault anything on the coding side of things, but gameplay needs tweaking for replayability because somehow i doubt i'll be playing this again...
