nice game! I think it would be better from an education standpoint if the roman numerals were at the bottom of the circle and you didn't include the spelling of the chords. I like that you added 3 lives to make it more challenging and fun. Here is my game that I am starting to work on. It is meant to teach the concept of harmonic movement - movement by second third or 4th. https://editor.p5js.org/briancameronvoll/full/sCR6630hj It is in very early stages. I have only started learning to code a couple months ago! let me know what you think, I am still trying to think of simple ways to make it more fun.
