Music should be a big thing in a pirate game, I was glad when i saw that there were instruments but I was disappointed when I realised you needed ¨ammo¨ to play it.
The fact that you can find music notes around is fine, but the fact that they expire after ONE use is not okay in my opinion.
My suggestion would be to either:
-Make the notes last forever
-Make the notes last x amount of times
-Make a generic song that can be played even without notes
-Be able to make music notes
Good sailing!
