The 'play each level at least 3 times' achievement was a poor choice; instead of rewarding players for doing something more difficult - get the challenge at maximum difficulty on the first replay - you punish us by making us guess which levels we have to pointlessly play again. Very annoying.
Wait... I can't finish because I need to play through three more times to meet an arbitrary level requirement? How the F did finishing this game get to be a badge of the day?
