the glitchless categories already allow the use of some kinda buggy behavior, but this new bridge skip is, to me, the most obvious case of unintented behavior in the game since the wall clip. not only does it teleport you across like half the map, but it also plays a cutscene where karl m (the npc) is in a completely different spot than his actual model is in.
i'm honestly not entirely sure if i think it's a glitch, but it's close enough that i'd appreciate the clarity on whether it's allowed in glitchless or not.
i've recently discovered a new glitch, which can save a couple seconds in any% and upwards of 10 seconds in 100%, that i'm unsure about whether it's allowed or not.
i call it "pig bouncing", it uses the fact that the game maintains your vertical momentum between saves. the trick requires you to have a save file already set up at the final boss right before he's about to land. you load your main save right after he lands, and keep the bounce into the main save.
personally i think the strat should be allowed, since the entire main run is still in there and it's both a fun and quite difficult technique, but i realize there's no precedent here so i wanted some extra confirmation.
here's a run i did that does a pig bounce at around 0:20
