So i was just re-playing OF again for fun (not a speedrunner or anything), and when i walked to the electrified cage to do the glitch where you deactivated from the other side i completely passed trough the wall out of nowhere, i dont know how i did it but i have a screenshot to prove and my game is still running rn. i want to know if this can be of use in the speedrunning scene or something like that.

i found out how to do it

So i guess theres a crack in the geometry in the corner of the concrete wall and the rock wall which you can pass trough, it doesnt seem that you can move anywhere except going back. Heres a video showing it
