Hi 👋
Love that you are taking accessibility in consideration!
I think you can find a lot of information and inspiration on the site of the good folks behind caniplaythat. They offer guides and video game accessibility reviews.
I attended a talk once from one of the developers behind Chicory. I know they've done a number of things to keep their game accessible. caniplaythat has also written a review for Chicory.
Hope this helps 🙂
