Thank you Icehouse. It's fair to say that my focus was shared between the game and development of the library which supports it.
I think right now the game is a decent demo for Balladeer. And it's also a work-in-progress which I might continue with. Since it's on Github, it's there for others to tinker with, too.
EDIT: This was a reply to Icehouse's post above, but for some reason it keeps appearing down here.
