There is one question that I haven't entirely figured out how to ask but am curious about -- if we let you adjust the octaves, and if you select the correct note but the wrong octave, would you want the game to highlight the note as "green" (correct) when you submit the attempt? Or would you prefer to have to guess the right octave along with the right note before the answer is accepted?
(Unrelated side note: I am a desktop person, and thus surprised that so many people are playing it on their phones, haha. I'll have to check the google analytics for that.)
