Looking through my speedrun there's no way I can figure out how this glitch works (5:15 - 5:43):

I have this glitch is obtained by leaving the elevator during its activation, and when the location is lost, then you need to exit the game and come back, should transfer to another point of the location

Do you have any ideas on how to save even more time with this glitch, and what rooms it can be used in?

Check this run please
