It is fine as long as you provide a screenshot when you finish or a video if necessary (see rules for when videos are required).

No. It wouldn’t invalidate your run.

It's whatever you feel comfortable with. (Also if you're asking for keybind suggestions it would probably be useful for someone to know what you're playing the game with—i.e., keyboard or a controller)

So all checkpoints. Do you have to actually touch every checkpoint or is this just any % without skipping checkpoints? If it is the latter then the name all checkpoints isn't really an accurate name.

same as right now really

We were planning on adding a NMG and all glitches categories (i can't cause i'm not a mod)

Oh sorry I didn't mean to be rude. Didn't think about that.

if you do a glitch it’s not glitchless...

So wait. Are videos required or what?

yeah people used to do that in earlier runs but it’s been patched as far as i know
