I still don't know if my theory is correct but id love to be corrected. this can be useful for only 100% due to it being a glitch. agian still havnt done a run of it (nobody has yet lol) but im excited to see. this is a very difficult trick so i doubt anyone will use it... unless (done in 1.1 but should work in 1.0)

anyway enjoy ig

also as a note from what ive tried it can only be done on tiles that damage you, but to be fair i havnt tried this on a normal wall
