Well, rather intruiging. Sadly I got stuck in Night 2 pushing into that conversation between Owen and the Doctor. At the and I found myself facing down and unable to move (I could still rotate, what you see on the screenshot is a door). Maybe I triggered the scene from a wrong location?
Edit: After watching the walkthrough below I'm rather sure the sequence was triggered to early. I think I've checked the closed door one stairway below - which was locked as in night 1, and when I went back from the the dialoge was triggered below me.
(Another minor bug was: I found the bunny before talking to Dr. Gray. So he was still standing there at Night 1 and I could have the bunny related dialog wiht him.)
