I can't tell you how much I enjoyed the relative lack of a tutorial and 'front story'. I've gotten games and then sat on them for months because I knew I'd need a good 45 minutes to even start playing the game and just never had the time or patience. This game was just such a great "pick up and play" experience; and it let's you learn a lot of stuff on your own.

The puzzles are amazing because they feel very natural. The game doesn't go out of its way to prevent you from "cheating" or solving the puzzle however you like. But it also doesn't feel like it was intended for there to be more than one solution. The intended solution is usually clear after the fact (even if you've solved it some other way); and it seems like the solution, but any other solution is also accepted. It feels as if I've really stumbled across this puzzle, and even if I can't figure it out, I can figure SOMETHING out, and that's alright.
