Members - Tower Descent mod for Amnesia: The Dark Descent

You play as a german climber, who decided to get to the top of an old castle, near his village. You're really tired by the time you reach the top, you need to rest somewhere. Luckily there's a hatch which leads inside, where you can sleep for a while. Once you wake up, you find out something's wrong with the hatch, and you're stuck.
