Played it last year and think I even posted about it on the old forum. Its a great game in my book because it creates the environments well, game mechanics aren't overtly hard to grasp and the puzzle-oriented gameplay keeps you engaged. The only gripe I have with this and Limbo are that they're just too damn short. If I am not wrong this one actually worked its way up the ladder to a GOTY award nomination too and they rightfully deserve it.
