Some other info I found-
[This info may not be 100% correct, it's just anecdotal evidence from my in game testing]
The girls CAN NOT kill you when they are standing in your doorway, with the exception of Ari if you let your sanity get too low. Once they move to the window is when they can kill you if the door is open.
Nile- if you start to fill her meter then switch cameras before it is full, it will knock out the camera feed of her current room.
If she is standing in a doorway, even if her meter is not full, she will not kill you.
Ari- She will block the girls in the window from killing you while she is standing in the doorway. She CAN kill you from the door if you let your sanity drop too low.
Maddy- she will randomly block one of your cameras, just hit the microwave and it will move her to the microwave room for a few seconds so you can get the task done if she is blocking it.
The microwave has limited uses, i believe 3 or maybe 4, then it breaks. Towards the end of the night she will come into one the the doorways and block you from closing the door. During this time the other girls who are at a window will be able to kill you, but i don't believe Maddy can kill your herself. Just hit the microwave and she will go away so you can close the door.
