Two of the complaints I saw about icebreaker were the graphics were bad and that it is too similar to cut the rope. For one thing, nitromes style is supposed to be pixelated, and you should be able to tell from the sharp colour differences between pixels. The original pc version of ice breaker was created a year before cut the rope was. I have had no problem with the game and love the ways you have to solve the levels.
