I'll tell you what I can remember from the gameplay footage I saw in the game.
You're in a old-style city, and if I remember correctly, you're like a detective or something. The game is styled like Amnesia: The Dark Descent, but I know that's not what it is. While walking through the mildly populated city area, there seems to be this monster thing following you secretly around the city and watching you, often making frightening (Fix: Pants-shittingly-scary) random noises as you progress. In some point in this level, you find a little girl, who you follow back to her home. Once inside, you're waiting for her father to return home. While waiting, there are noises coming from upstairs. Having gone up to search, it gets increasingly more dramatic as you check each room. Making your way to the last room, apparently you run into some kind of demon-thing, suggesting the man turned his wife into it. It breaks out, killing the man as he returns home(I believe), and knocking you unconscious. I don't remember what happen to the girl, but I fail to remember this game.
Two things come to mind: Penumbra, and Amnesia, but I don't think either of these are hit.
Please help me remember what this is, I beg of you. I want to play it, badly.
None.
