Utterly fantastic.
This is one of a very small number of games that I've sat down and finished in one session.
Completely engaging, thoroughly intriguing and more than a little gross.
I'm not a clever man, i don't do puzzles in games very well but his was fun, nothing tough enough to make me feel stupid.
The story here is was main draw for me. Drip feeding it to you perfectly.
And the atmosphere and design back it all up beautifully.
