Very nicely done, great music and artwork.
You might want to have the VFX preload in the splash screen as there was a hitch the first couple times I missed a note during the "combat". It also took me a moment to realize I was moving specific items in the bag when trying to get the flute below the fill line, but that might have been my own cluelessness.
Bonus points for all the nice extra menu pages, and multiple option submenus, rarely seen in a jam game, well done!
