I know it's probably been said before but the collision detection of tacks with bloons isn't that great. It's obviously a hit, but the game registers it as though it missed. Fix that and I'll 5/5, till then, 4/5
the Tab+enter command fails. Other than that a fun, addicting game. 3/5 till you fix the whole "tab" button thing. (perhaps change it to enter and shift?)
Some weird glitch just happend: I had 7 MOABs on screen and my super monkey, saw shooters, and rockets were all blasting away at them. then, they all just dissapeared at the same time and it said I beat level 64
