I'm really terrified of horror games and it didn't help that I played this at 1am. Truth be told, I couldn't bring myself to finish the game, but I can't say I wasn't impressed by the sheer amount of detail that went into every aspect of the game. From the start cutscene, to the use of shaders and environment, that was amazing.
I wasn't a fan of the controls, but I guess having bad controls adds to the spookiness of horror games.
