THIS GAME IS SO AWESOME. I'm in love with this concept and would beee so interested in playing an expanded version of this game.
This version is obviously short, sweet and pretty basic - I still found myself immersed and excited to fill out the song.
The dev in me is thinking about how cool would it be if one could upload their own midi files and play them!
So much potential here, please consider taking this idea further than just this jam.
And if it needs to be said, super super creative take on the theme, well done indeed!
