I think this game has a cool concept, and I am intrigued to see where you take it.
I found it difficult to figure out what I was supposed to do at first. For example, I struggled to open the market/mayor menu after sailing to a port. I pressed random keys for like two mins before I tried clicking the button. Similarly, it took me a while to find the boat upgrade menu. I did click the logo, but it looks like you have to click a specific part of it.
It would be great if you put more explanation into the controls and menus in the description. It would be even better if the instructions were part of the game. It would also be good if the menus could be opened with button presses as well as mouse clicks.
I thought the menus worked well. I tried to find bugs, but they seem pretty solid.
I'll come back for another play in a few weeks.
Cheers,
Cain
