Absolutely gorgeous art and a very intriguing experience. The key and the detail on it really drew my attention for reasons I can't quite explain. I almost felt guilty breaking the machine with my curiosity! That is, until the spooky image appeared to chastise me!
I do wish the game auto-played in my browser though. I read the description text entirely before clicking "play" and it removed a bit of the wonder as the same text was presented to me again by the game.
