I think I've found a bug or at least a softlock in the game. If you use the rope and hook in the solitary room and deposit the blue key prior to getting the key within the cells, you can't pick up the hook and rope without getting trapped. Beyond that, if you choose to collect the rope and hooke, you get locked in the room, unable to rope up again or open the door. This is the only game breaking bug I've seen up to this point with some collision errors but those aside this is a fantastic remake!
