I really appreciate the help, thank you! But I am not getting it a single time with your method. I'm sure that it works, I just think that I'm not doing it right, maybe I aim at the wrong window.

Also, what is a purple y-patch? I think they are the purple areas on the floor, correct me if I'm wrong.

I would like to see your path in action, to see what I am doing wrong.

Thanks again!

Edit: Thanks to you I discovered that I can jump a few frames after touching the ground, I thought jumps had to be immediate. this has helped me A LOT.

I don't have so many problems with my route anymore, but i still suggest you to show your route for the speedrunners who have issues with this skip! :)

This is my main problem with the ascent route, sometimes I jump well and sometimes I don't (I almost never succeed).

I attach a clip where I jump where I should (or so I think) and I don't get there.
