On every wr glitchless speedrun video, when someone highjumps or does something like that, everyone in the comments say things like "highjump is a glitch lmao remove glitchless in the title." Seriously what counts as a glitch, this thread would be really useful for new speedrunners that want to speedrun this game (like me) but get confused about glitches. Edit: You can check Clloy's ToES speedrun if you want to see those highjump comments I talked about.
Anything that seems unintentional (with the exception of regular high jumps and ladder flicks (because mega is weird lol))
Everything that is considered a glitch: Laugh clip, lag clip, wallhop, corner clip, /e dance2, lag laugh.
Lag and laugh clip aren't allowed in coil runs
Lag high jump isn't a glitch.
Using lag for anything is a glitch. Doing any sort of clipping is a glitch. Wall hopping is a glitch. Fling is a glitch. Lag and Laugh clips aren't allowed in coil runs. Very RNG things like luck clipping or ragdolling+bouncing for your advantage is not allowed. Glitches that you are meant to do to beat the tower are allowed anywhere.
