This game had a very foreboding aura, the music and the presentation all make you feel like you are in an oppressive world that is slowly eating at you till it consumes you. I think it did what it intended, and the videos in the game were really creepy and added to the atmosphere!
Suggestion, the sound of the voice did become a bit annoying after a while, I think if it wasn't there or it was a bit less repetitive it would have elevated the experience even more!
As a horror fan I would say this is an overall great job!
