so I can schmoove and groove on lvl 0 right up until the jump from sword guy land to the first platform on glitchless. I always come up just a bit short of the platform heighwise. Help?

i assume you avoid getting the doublejump , then you need to jump off from the button. that means get ontop of the button and jump from there. ( ofc with a bit of windup)

You don't need to jump off the button, see the WR. Just do a normal crouch jump or SJS, and crouch at the end.
