After grinding for a while, I started getting quite used to the route and thus the movement is getting much more optimized and fluid. I also found out a new route in the room with the Knight, after the 1st button. You can actually jump up there, without having to go with the bottom route. If you're too fast though, you'll need to wait a bit or you'll get hit by him. But it should be faster regardless, hopefully at least!

I was also either too fast, or slow, getting up to the damage boost skip section. I had to wait a bit to attempt it, so if one can be just a bit faster you can save additional time there as well. Furthermore for the 2nd button part, I actually waited behind the Knight to avoid getting hit. I know you can get super lucky and squeeze past him from above but that is rare that it happens. I also messed up dropping the box, doing it in the wrong direction due to control stick shenanigans. I feel like this part is the one that can probably improve the time the most.

The rest of the level is pretty good and nothing to really say other than the Lava + Spike cycles can perhaps be optimized too if one knows the cycle or risk it all and yolo it.
