As of right now, glitchless and no WW would essentially be the same category (No WW will likely probably actually be no menu storage). Depending on how things evolve in the future, that would be something to re-evaluate.

We are planning on having a No WW category.

Probably a good idea. I haven't played it yet myself so not sure what the best way to go about it is

You can just wiggle the stick back and forth, but as Bamboo said, you don't really need to worry about it. Generally what we would recommend to new players is to only worry about pumping on stairs at first.

I'll take a look at the mislabelled runs and will bring this up to the rest of the mods.
