I made a video showing some glitches. Only useful one is probably going to be the Momentum glitch.

Also also when i clip in blue world level 10 Into the ground below the flag, I Get the animation and that animation persists after you die in the level. Could be useful info somehow

the out of bound ones (clipping woth boxes and eith zippers) are known, and so are their effects the flag animation can be done by jumpping over the flag, no need to clip, and the zipper hyperjump is also known

now, if you could join the discord and explain WHAT IN THE WORLD WAS THAT BOX LEDGE BOOST, we would be all very grateful

and also, no it is impossible to TAS this game lol unless you have Hexoboy emulated on Linux and LibTAS, that only runs on Linux
