I would say that the game is an absolute gem! I was rewarded for the money and time I have spent on this game. If you love atmospheric horror-sci fi puzzle solving game than this is a must have. Every single time I thought that the story can not be any darker/twisted I was so wrong! The puzzles are fairly balanced difficulty wise. There are large areas to discover and many contents to read about passed events to unravel the many tragedies that happened.
