To be honest I didn't like the game, at the beginning playing the game was giving me a headache (a real headache), I think it was because of the camera, lights and those effects that they use in the game. Then, it becomes a bit better. However, those sounds inside the first character head was so annoying. It's not a normal game and it's not something that I want to play again. Also the ending of the game was so poor and bad.
I bought this game because if its good reviews. But in my opinion it's a poor game.
You should have some kind of mental problem to play this game!
You are playing a game to enjoy, not to be annoyed.
It was waste of money and time for me.
