Recently, Nintendo shockingly acknowledged Mario Maker 2's existance by adding a new ninji. My question is how will this affect the All Ninji's category?

Will all current submitted runs be removed or will the category remain the same and not include this new one?

Under other notes, the rules say that "Runs must start from a fresh start with 0 progression."

So I noticed a new category was added to SMM2CE Nuzlocke%. Just to clarify, can we upload videos of our runs bits at a time so lets say one day I upload a video of me beating 50 levels and then a week later (same run) I beat 25 more levels. Can we do it like that so that we would be updating our score, or can we only submit our runs once we game over?
