Here's what I've been up to.

This led me to look for other places, and my next target was the Drowned Abbey, but with a high jump. Unfortunately the high jump didn't keep the speed, but that didn't stop me from looking elsewhere and I found a smaller skip, where I realized that the speed kept even after landing.

After many runs, yesterday I found that a glide keeps the speed. I realized it could be used to skip the bell puzzle in the Silenced Cathedral, so I went to try it out. I still struggled a lot to even get it to work, until tried doing it towards the camera instead of away and lo and behold I got it.
