A very impressive game. You cannot say before trying it whether it will capture your attention till you finish the game; but it has all the chances to do it with its unusual design and atmosphere. I truly enjoyed it.
An interesting and challenging game, which is at least as enjoyable as World of Goo. It is different in style, but leaves a similar feeling of joy when you beat it.
I've seen this game on my friend's computer and took several moves in it. It is very unusual and dark. When you start playing you get fully involved. The only minor inconvenience here is that it is commercial and there is no way, unless with the help of your friend who has it, to test it before buying.
