I just beat the game. This is the kind of horror game that should be played one in a while.
The story of the game keeps you interested during the entire game. Even though, it is very short game (6 hours), it feels long due to the gameplay. You mostly have to use the night vision of the camera to see in the dark. That makes the game hard to be played for longer period of time because the keep you stressed and with no environment to really appreciate.
There is also some sort of repetitiveness in the game, however, it is very enjoyable.
