I was wondering if I was the only one who heard about this game. I did buy it and I absolutly love it (I'm at 53% of the game).
I recommend it to every person that has read some Lovecraft and liked it, this game feels like you are reading one of his books.
I'm realy impressed by the way they could manadged to implement a sanity system and health system without having any hud on the screen
