This game seems a lot too easy. It doesn't speak well of the game's difficulty when the last achievement you pick up is the one that asks you to play each level three times, and that that's because, apart from levels eight and below, excluding seven, every single level required exactly two tries. And, to be clear, that's one try to beat the level and get the special challenge simultaneously, and a second to beat the level with the difficulty at its highest. It's the bare minimum of attempts, and that's really not where you want to be on the last level of the game, or most of the others.
