so, my idea was to get to the section of the game where you can do the glitch to glitch through walls except instead of going through the main path of the story you would walk out the cave straight to deaths cave then menuing to turn off the wall glitch then making it, so you are unable to enter the cave but also unable to get back out because of the reaper blocking your path. if you want to see I have also made a video of me doing a "speedrun" of it on my channel though it's more of a proof-of-concept video than anything.

Heres the link if you want to check the route

don't know if your still taking suggestions for categories but was wondering if there could be a softlock%
