Provided you understand that a book, movie, game, or other work is intentionally brutal, frightening, demoralizing, or has some other unpleasant effect on the psyche-- and provided you decide that you like that genre of horror-- then go ahead and read said book, watch said movie, play said game. But there's no point complaining if the work makes you want to take out your soul and wipe it on your pants: that's what it's for.
Even if you aren't into that, this game is really gripping. I'm no expert critic, but I liked it, and I don't normally like unpleasant elements.
