I love pirate games, I can never get enough. This one was fun as well, apparently I'm the best one-man crew across the seven seas.
It was fun to play, I especially liked how the music changed once I got into combat, so I knew when I was attacked by the third ship. Were there any increase in difficulty, like more damage or change in tactics? I saw they got better in manouvering, the first one didn't even seem to move, the third one was doing spin-and-shoot tactics, while the fourth one seemed to constantly avoid my line of fire. I also liked the peaceful island in the end.
One thing I'd definitely recommend is some indication of what I can interact with and how I can do it. I saw the text appearing for the sails (though I didn't what that means) so after that actually had a harder time realizing I have to click on the helm and the cannons as well. Tried the paper with the dagger as well, but that didn't seem to do anything. So yeah, some more indication for interactables would go a long way!
PS: I even managed to board the enemy ship, although there wasn't much to do there and they sank my ship soon afterwards:
