The only flaw I can see with this game is that we should be able to pick what color circles our towers come with, instead of waiting what is potentially a VERY long time for the right ones to randomly appear. Some of the waves can get very time-sensitive.
Oh wow. This game... this game is magnificent. The game mechanics are executed PERFECTLY. It's frantic, fun, and there are lots of little details that make it VERY user friendly, like the ability to midair jump shortly after you walk off a platform.
The controls are way too slippery for the precision required here. I know the only color in my outfit is green, but that does not mean I should have the foot traction of Luigi!
I keep running into a game-breaking bug on random days where EVERYONE leaves the store unhappy the second they touch the CD racks, no matter how well stocked they are.
