how did you manage that? I see the door is still closed so that explains how you are not triggering the cutscene to end the game but how did you get out there?
Glitch through walls: I think when you turn your head you’re probably manually changing the player’s rotation instead of letting the physics do it?
Climb up in corners: idk just kinda jam yourself in there and you’ll move up
ALSO I think the point you’re rotating around when you turn your head is probably offset in front of the player’s collider?? Just a guess
