I enjoy horror games quite a bit, but I like to stick to "white-hat" games, where you overcome evil or learn about yourself, and the final feeling is generally uplifting. This is not one of those games. While you can choose your actions, it is a lot like Vespers, where rushing along will lead you down a path that leaves you feeling uncomfortable and unhappy.
Otherwise, the game is well-made. I just can't recommend it to others; for a game with a similar feel and less squick, I recommend the Twine game Eidolon.
