I'm playing 0.75 and I know that the doors have limited power so I waited for the bunny girl to look through the window before closing the door. She came in through the closed door anyway. Is it even possible to win?
In regards to this in case you might still be wondering the pig toy on the desk gives you sanity back when you use it and you need to balance using that and looking up at the vent while the door is closed but using the toy too quickly breaks it so watch the red bar next to your sanity
