This one jump will haunt me, I think.
Brilliant 1900M method, much easier than mine. Very nice!

NP!
Also wanted to mention for anyone else reading this, the main methods that I tried for the gosh dang one jump were corner kicking off of that corner and continuing from there, dashing diagonally up from the spring onto the wall, and getting onto that platform to the left with the spikes on it. For the first two it left me with no dash, meaning I couldn't get any higher than a single wall jump. For the walking on spikes, There's nothing much else to do considering I can't jump off of it...
