so can you equip a different avatar to get a different hitbox so like you could touch the portal sooner because your long arm touched it or you would be able to stand more on edge of the platforms and it could help beat the run faster i think but i'm not really gonna use this it is just a question

There really aren't any rules stating that you can't customize your avatar in a certain way. So I assume it's allowed.

Technically, dances are being used to alter the hitbox aswell. Since the mods are strictly against the use of altering hitboxes, I'm assuming this is not allowed.

only if the item used is free in coils, ihg is the act of using different avatar to go higher with coils preferably do not as it will just complicate things further, thanks for asking :)

ok then
