In the room where you have to fight a few enemies before spinning it around, you can shoot the toggle for the spinning and dash quickly into the rotating room and ori will be brought around, meaning that you don't have to run through the room and will just start on the other side.

Yeah it's a fun trick. For speedrunning it's not too useful unfortunately, since being on the left of the arena lines up much better for a wavedash, mostly it looks cool.
