I found a way to go out of bounds, at this point it isn't very useful since you can't escape, but I still wanted to share this with the speedrunning community since there could be a lot of improvement to make and use this as a escape method.
Dude, that's amazing. Nice find.
I've known about the possibility of a glitched speedrun with the Item Corruption glitch, but this seems like a much better way to go about it.
I'm gonna do some testing with it, but I suspect you could trigger this in any number of ways by climbing on top of an object on the same frame you interact with another object. And I'm definitely testing if you can trigger non-perimeter escapes while the glitch is active.
And I wonder if going underground clears the glitch in the same way that going into the vents does.
