Do I need anything extra to do that? I can't see the choice anywhere in the menu.

Hi! I've never speedran a game ever, and these are my first ever attempts.

When I'm watching other's speed run I seem to get very easily lost, so I just made my own route, which is pressumeably quite slow, and just trying to cut back time in new places every new run. Right now I'm not timing it, but my last run ended on 1h 3m on the in game time. I'm doing any% nbs

However I'm seeing a few glitches that I don't really understand and googling unless I know the exact name of the trick hasn't really helped. It just tries to teach me basic intended mechanics, like I google how to skip Nestor and it tells me that Nestor is the only non skipable dragon and it's like, I've seen you guys do this.

Firstly, how do you skip the cutscene for Nester at the start? It looks like people are jumping as it starts or something but I just don't get it, I've just been skipping him, but if I could get him as a dragon, I know exactly where I could make up some time.

Fairy proxying. I don't know if I just need to find a balance, but I don't seem to be able to find a middle ground between being shot up so high that if I want I can go out of bounds, and two low to get it right. And on other's runs I'm seeing that people seem to get the proxy and then jump again, where as I've never been able to jump after a proxy and I just start a glide into the wall.

Wall gliding is another one I'm struggling with, as far as I can see it's easier with a higher framerate, and my computer sucks, so it might just not be good enough, like I lag in the dream weavers world. That's just as straight forward as finding the right angle in the wall and gliding as normal yeah?

Finally, how do you skip the levels in the Gnasty Nexus or whatever it's called? I've seen people do this, but I'm still just having to punch the levels out as quickly as possible.

Also I'm playing keyboard and mouse, is this going to slow me down and screw me over? I know that literally no one else plays that way, but I don't have a controller and lowkey you seem to be able to make a lot tighter turns with the mouse.

EDIT: also does any% nbs have any rules on using the map? I'm using the map right now to help with route learning and aiming my landing with the excessively high fairy proxies.
