To me this is a survival horror masterpiece, the puzzles were hard enoujgh I had to whipo out a pen and some paper, very challenging at least on hard which is what I played. You have to be smart about your resources up to the end. Which is nice cause even being careful with resources I was low on certain things a lot. Added to the thrills and tension. I enjoy the world a lot and what lore we did get, I just wish it was slightly less cryptic in certain areas. The sounds in this game are great which is very important for horror.
