In order to be able to repeate this route, you need to understand some basic movement mechanics

If you dash horizontally and right after jump, you will get horizontal boost

To make hyper you dash horizontally and down. You have less upward momentum than with a super, but you fly horizontally much faster and farther

If you wait a couple of frames after dash, you will regain dash while keeping your velocity

It's the same as extended hyper, but your vertical position is higher

Also you can dash in opposite direction while holding movement in the right direction and still get absolutely the same result. Works with super, hyper or wavedash

Just dash up along the wall and jump to bounce off wall. The later you jump, the higher you'll bounce

You can throw jellyfish and regrab it with dash. You will get a massive boost

Jump horizontally to the top edge of the block, hold grab and press jump while holding movement when you collide with it.

Bind crouch dash in the settings. Some of the kill colliders have textures much bigger then their hitboxes. When you in crouch position, Madeline's hitbox about 2 times smaller (from 9 to 4 pixels). So you can jump through some obstacles.

In order to execute this I highly recommend to bind 2nd jump button.
Spikes can't kill you if you move in opposite direction. You can kinda wallbounce of the wall even if there's spikes. You just need to press 2nd jump right after collision with the edge

This is pretty hard compared to other dashes. So you can dash ↘ at the edge of the block, jump right after landing and dash ↘ after about 5 frames. If 2nd dash is too early - you'll bounce really weird on the next platform. Less airtime = more speed. So you want to dash as early as possible in most cases. If jump too early it will be counted as extended hyper. Ultra will give you abnormal velocity boost if used properly.


Chaining ultras will make you zoooop.


And even more if you ultra from moving block


Also, speedrunners usually do some trick on this kevin block in reflection. This is not ultra, but uses simmilar mechanic of keeping momentum as ultra from moving block. If you short hyper + immediate jump (just bunnyhop) on kevin, Madeline's momentum increases 1st time from kevin, 2nd from hyper, 3rd from b-hop and 4th time from kevin. Just 2 jumps and you'll fly

Using this obiously non-tas speedrun, you can point every mechanic above on the video and try it yourself!
