This is a custom story for Amnesia: The Dark Descent
Well, this seems to be a retarded puzzle map or something, after getting the key from the dog, you are given 0 hints on how to progress, the key would indicate that you open the two doors available to you, but it doesn't work on them. ????

That was pretty dumb.
Well, I must say I really didn't like the puzzles.
