So i know the community is having a poll on this, but id like to make an offer where there could be 2 categories for story mode: Story Mode No Death Abuse, and Story Mode Any%. Any% meaning you can use luigi on some levels that are too long or are a waste of time in a speedrun. No Death Abuse meaning you cannot use luigi in any levels whatsoever. Im getting this idea from the tropical freeze runs where they allow death abuse in a category, just an idea, but mods you can do as you wish :)

Not a bad idea, depends on how popular story mode runs become.

What if u could use Luigi for individual levels? The first one that comes to mind is underground coin collecting which is faster and easier with fire flower.
