Show HN: I created a game to memorize guitar/bass fretboard intervals

Hey all About 6 months ago I shared a game I made to help guitarists and bass players memorize the notes on the fretboard (Fretboard Fly). This time round, I’ve built some games to help you memorize the fretboard intervals as well. A lot of you also mentioned that the game was too hard so I also built courses to go along with the games.

To be completely upfront about this, I’m trying to turn Fretboard Fly into a paid product but still stumbling my way through it. For now I’ve made all the intervals courses and games free to learn and play for at least a few weeks. In exchange I’d love to hear feedback about what you would want changed or added or if there’s anything you find confusing.
