I just found the glitch while playing, and realised that you can abuse it in speedruns. I would still say that Any% No self dudgeon should be the main category due to being actual skill.

Hello everyone,

A recent Any% run used a glitch to spawn into your self made dungeon while opening a level door. This allows you to beat every level without having to play the actually level. Because of how broken this glitch is and how easy it is to replicate, the Any% category has split between using the glitch and playing all the levels in the intended way. Hope you all understand.
