A Mandolin Fretboard Game

I have started working on a game to help people strengthen their knowledge of the mandolin fretboard.
The game presents challenges to find a note or identify a note and for more advanced users, to find or identify an interval.
For finding a note or an interval, the user can click on the fretboard or enable microphone input in the advanced settings.
The game can be accessed at https://mandolingame.johntreacy.com
It’s fairly intuitive – the initial settings are a right handed mandolin viewed as though you are playing it – looking down the nearest string pair is G. You can adjust it to be left handed or as though you are viewing it sitting across, as in watching your teacher play the notes.
Additional instructions can be found in the About box at the top right of the app.
I am making it freely available, but if you would like to donate to support the development of the game, there are links in the About box.
