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.

You need to coyote jump off the ledge, meaning you have to land and move off the platform for less than 1/10th of a second. The easiest way I've found (after dozens of attempts) is aim for the middle window of the building near the bridge, and bhop to the closest purple-y patch near the ledge, jump to the purple-y patch and then aim for the little protrusion (like you did) and wait to jump just a tiny, tiny bit so you nearly fall off, then jump.

Your route should also work (and may be a bit quicker), but you need to make sure to wait a tiny bit before you jump the last time

It takes a LONG time, especially trying to pull it off during a run, but once you can get it consistently and know how to do it, it seems much more forgiving than you would think. [I'm sure you know this but] Once you get past the really hard jump, you don't have to keep bhopping, the game doesn't save a respawn point there. You can line up the jump much better than this one.

The best thing I can recommend is just keep practicing and seeing what others are doing. I could post a video of me making the jump if you need.

Happy speedrunning!

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! :)

Yeah! Luckily, I spent hours upon hours running this, so I have plenty of reference videos.

The purple patches are what I aim for as reference points.

The second video (labelled 2) shows one where I didn't hit the first purple area quite right, so I buffered to land on the second patch in the right way.

You can see in the first video just how forgiving the window is--once you've gotten the strategy down.

Hope this helps. I have more clips and could probably make a new one where I look down; just so you can see where exactly I'm landing.
