the few extra masks the game gives you only really help if you can handle the difficulty but need mistake tolerance

Increasing mistake tolerance already increases accessibility, even if you still have to manage a tough platformer part.

Of course the options given are just examples to get it done quickly. Accessibility options can be a a lot more nuanced, even going as far as altering level structures to provide pathways for players that can’t platform.

The point of my post was that for all I care the difficulty options can go all the way to invincibility, one hitting every boss and skipping every platformer segment. It does not reduce my enjoyment of these games if other people can play the game in a way they want to.
