[PLAYING AS EMILY] I discovered this one by accident and i have it clipped if anyone wants to see it. Basically, i was carrying Sokolov out of the maze and i pressed on the wood-covered button outside his room and turned around, and i far-reached the end of the ceiling panel right in front of the door, on the edge furthest from the doorway, and glitched through it. Haven't tried to replicate it yet, but i got a good look at where I came through the ceiling and it was on the edge of that panel, right where it connects to the windowpane thing. If somebody can do it regularly, could save time from having to climb the stairs, and even leaving the maze directly.

can confirm, just experienced this same glitch and can replicate it by moving on and off the button to trigger the wall moving up and then far-reaching into it at a specific time. im not a speedrunner but after looking at the last world record for any% this is definitely a timesave, just a matter of practicing the timing of the wall enough to be able to do it without getting crushed.
