One of the best short story games you will ever play. It will probably take you just under 3 hours to beat. Very beatiful graphics, funny/wierd conversations, and bit of a twisty story. Highly recommend if you have a few hours to spare (would recommend to play through the whole thing in one sitting, makes it better).
As far as the price, i'd say pick it up while it's on sale, not saying it's not worth $20 (very much is), but it's a quick playing game.
Solid 10/10
