Is there a requirement for how old your account has to be before you submit a category request?

you have to unlock all of the costume doors. Timer ends when you get the last costume door moon.

It could be a PG category or it could start like an any% run

You start like in any%, and you have to hit all the cacti sets in sand kingdom The timer ends when you finished the last cactus set

It's like a regular any% run, except you have to collect each moon while in midair.

Timing would be the same as any% timing

If you touch the ground while grabbing a moon, you have to reset your run that moon doesn't count towards your total 124.

There could also be Jump% ILs for each kingdom

No 2P or amiibo
