Nice game with a solid story. Graphics are fine yet the game is poorly optimized. Here running a 980 Ti and 16gb RAM it gets really laggy. Back to the story I have to say it is a very strange and hard one. Good choice for a game. As regards the gameplay there are some parts which lack indications plus puzzles are not always that simple or easy to see.

Overall I would give it an 8/10 really worth trying and better getting all achievements done =) A must if it is on sale.
