Don't change a thing. Let the player struggle through it. They will figure it out over time and be better off for it. This comes from experience as I'm dyslexic and it affects number and letters. Gaming helped me a lot. No one changed the game for me and I struggled but I loved the game so much I put the effort in. Something I didn't do in school. I didn't find out I was dyslexic till I was in my first year of college. That's right gaming got me that far. Once diagnosed I was taught techniques, took years to perfect and when I went back to finish what I started 4.0 in every class. I just took what I did to learn games applied to my classes. I'd come over book reading all kinds of ways till it made sense.
