Hi! I've been watching a lot of the no OOB speed runs, and have found that other than the sensory jump some use a regenerate dash of sorts.... they press dash and regenerate at the same time (or something) and just go really really far horizontally. I've tried it on my game but couldn't figure out how it works.

You have to dash into a wall, then hit the opposite direction and regenerate before actually hitting the wall. The timing can be really finicky though

Edit: also, this is called Wavedashing, and it's in Skarfelt's Movement and Tech Guide
