hey, sorry to hear your struggling!
i'd like to make the game enjoyable for a lot of people, there's a few people who suggested colored runes at this point. I can put some thought into making an option for that, or perhaps simpler/clearer rune shapes as well.
in the mean time, I just added a gameplay hint section on this page, just above the roadmap. theres some stuff in there that makes the game much easier if you know it.
