Rated M, eh? WARNING: Game may contain explicit scenes of little bubble monsters blowing up. Very Graphic, not for faint of heart. In any case, this game is pretty cool, just not my cup of tea.
Rainbow bullet upgrade is broken. Have to grind the first stage because the diff is to hard to beat the 2nd stage without more upgrades. I was playing this on easy too.
I love upgrade games and i really do like this one. Many worse games of the same kind has passed so why shouldn't this? 4,5/5!
