I don't have dyslexia but I do have an astigmatism and I had to pass over three games and struggle through some others because of font choices, so I'm glad to see someone else brought it up. Certain fonts look great as titles but don't work in big blocks or at smaller pt sizes was the most common issue.
I know on https://www.w3.org/WAI/test-evaluate/tools/list/ you can sort by "document" on the left and it gives you a few options to check PDFs and other files for legibility by screen readers and other accessibility devices.
