Of course, feel free to ask anything! I really like your game and it would be a pleasure to help you polish it! ^^
That's perfect! Unique pattern for every colour, player chooses which one(s) to toggle. To me, with purple enabled, I have no trouble left at all telling it apart from blue, thank you for the setting! =D
You should just make it more clear that the toggles in the settings are clickable since they are only lines of text.
