I really think there's an interesting ship management/fishing game buried here somewhere. The art style is very endearing and it makes me want to fish. Unfortunately, and it's possible I was missing something, I never really got to play that fishing game.
I think something has to speed up between fishing, repairing the ship, or putting out fires, perhaps all three, while the rate of storms, fires starting, and water rising has to go down. As it is, I start fishing, but I can't look back to check the state of my ship without letting go of the rod and having to start over. So I just commit to the one fish and then by the time I've reeled it in, the rest of my time is devoted to trying to keep my ship from sinking. Personally, I would make putting out fires and repairing the ship take significantly less time, since the core of the game is focused on the fishing.
There's clearly a lot of ambition behind this project. Keep going!
