Always room for the greatness of Bach! Really great idea as a way of educating people of contrapuntal music through the medium of a game.
The timeline UI was a bit buggy and awkward to use at times, so spending some polishing time wouldn't go amiss. I'm also not sure if the "Next Excavation" button is bugged, or if its meant to load another part of the same composition, but then the phrase blocks bugged out.
I think it may have been helpful to have a real recording of the tracks be playable from within the UI, so people know what the goal is. As much as I love Bach, I must admit, I can't remember his inventions off the top of my head!
I had considered a game featuring music but couldn't find an idea that worked, so congratulations for pulling it off and submitting it to the jam!
