Im trying to do the jump at the beginning of the run, when you grab the vase, leave the room, turn left and go into the corner straight ahead next to the door on the left. I cant seem to figure out how to do it, iv done all sorts of jumping and throwing for around 20 minutes and i cant seem to do it. its in the any% number 1 run if your interested.

If you are on v1.3 then it most likely wont work because I think it was patched out so you will need to down patch your game for it to work most likely
