Well I think I found another one. There’s a song in the cave that I never picked up, and apparently you can’t go back if you miss it. Sadly, I overwrote the save state I had at that point, so I would need to start again from way, waaay back.
I’m officially giving up for now, but may revisit some other time. Good game, I was just a little too careless with saves.
One last comment…I have absolute pitch (sometimes less modestly called “perfect pitch”) so expert mode was a breeze for me, until my fatal mistake.
