So I've watched a couple of the speedruns here now, and one of the key moves in a couple of places seems to be repeated wall jumping against a single wall.

I've tried to mimic some of the movements shown on the controllers/keypad, but am finding it very difficult to achieve. From what I can garner it seems to be that on doing the wall jump you press the direction away from the wall, then back to the wall and jump (jump, right, left, jump etc.) but I can't seem to replicate.

I imagine it's knacky, but any advice/tips would be greatly appreciated! Thanks

Update: managed to replicate it a couple of times, but not consistently. Seems after jumping if you select up and then to the direction of the wall, you'll loop back to it, to then do the jump again. I think I'm right with it being knacky, as finding it very difficult to do hah.
