You tapped into a niche I had no idea that needed to be explored! So far, out of the three characters, I enjoy Row a lot. An idea that came to mind is maybe being able to take another person on board, but at a cost. Having to take more food than items, etc, etc.
Having a fast forward during the nighttime if it's a scene that you have already come across would be neat too.
But overall, I love it! We need more cool pirate adjacent indie games.
