Whoops, I'm stuck on the scene with the ladder and three portraits! It won't let me move!
On that scene you're not supposed to be able to move backward, it purposely blocks you after the "scare" in that room, you have to keep moving left. Or at least I think that's what you were having an issue with?
Okay, I managed to play it all!
For some reason, it had teleported me into the walls at the bottom of that scene, and I was stuck in the wall.
I really enjoyed the game; I do the exact same thing, watching horror games when I know damn well I'm gonna suffer. I've taken to watching most of them on Youtube if I know it's gonna be Too Much. At least I;m not 100% alone then.
