Yeah, that makes sense. Given your account, it sounds like the 2D paradigm of the bibi-symbols (which I'm following) is fundamentally bad for interpretability with dyslexia, because it results in a lot of symmetries. Even when considering the population of people without dyslexia, I can't think of examples of vernacular human alphabets that have many pairs of distinct symbols that are identical under some symmetry. So maybe symmetry is an alphabet design antipattern.
