ability to disable punishment for death. sliders for amount of damage player takes, including invulnerability. enemy and player speed sliders. input options which allow more flexibility, eg ability to bind some of the chords (esp. dive kick!) to a single input.
and this is a little more involved, but: ability to checkpoint anywhere, or manually placed extra checkpoints.
another more involved thing i'd look into is adjusting criticality of timing for certain player actions, such as increasing coyote time. and, independently: adjusting criticality of timing for enemy attack patterns, eg making enemies which do a dive attack telegraph it in a more forgiving fashion.
rather than granular control over enemies vs player character, i'm a very big fan of what Chicory did, which is have an overall gameplay speed slider (when in action scenes) this approach is really helpful at least as someone with cognitive bandwidth limitations
it doesn't change any of the designed intention of the game, just literally runs all the underlying logic & animations at a proportionately slower speed
yeah that's a nice option! it maintains relationships between eg evade moves or travelling attacks and enemy movement. i also think it might work well to change speed during combat or precision platforming selectively, and have it be a different user determined speed outside precision situations.
that would be effective, too. i agree. the thing i'm looking for as a person with both cognitive and motor disabilities is to modify the intended gameplay experience as little as possible, adapting it so i can engage with it as close as possible to its own terms.
