About speed runs: If you think
this is exploitative, check out some tool-assisted speedruns, where they play games fram by frame. Who would have known that you can technically wall-jump in Super Mario Brothers 1?

Some people really dislike the more "cheaty" speed runs, but I find them entertaining in their own ways.
Anyway, since it looks like you have to get Sun Form, could you rocket up to the roof of the Sun Worm dome and go straight to the boss fight through there, or is that the part of the Veil without any rocks to rocket with? Can't wait to see how this turns out, if you end up doing it!
