When in any hospital, (all similar) when u enter through the front door, and take the first open room on the right side, the opening of the door is very glitchy, and you cant seem to walk through it in the first attempt, you really have to wiggle your mouse to walk into it, but on exiting the room, you get stuck in the same door again, character continues to run but doesnt move forward, but then, shoots forward throught the wall, into the room with the "unopenable" door right across the hallway, and you are stuck in this room - you are able to get out by running against the wall jumping randomly.
