Fantastic!
I actually took the time to finish the whole game (which took several hours of play throughout a few days). It's obvious a lot of effort was put into this game, judging by the great variety in level design, and features that were unique to eac level. It is rare to find a puzzle game with such a diverse set of levels that isn't a player-created map pack. Great game, and i can't wait until more of the sequel unlocks
