A great successor to Pushmo which rewrites all the rules to great effect. Since the mechanics of the puzzles are completely different in this one the game is fresh, while still being true to the spirit of the franchise. Puzzles in this one tend to involve fewer chunks, but be more difficult than a puzzle of similar size in Pushmo. This makes solutions harder to figure out yet easier to execute on, and overall make you feel more clever. It's all really smartly done!
