Was having a pretty good time but unfortunately had a crash around the time Grandpa starts talking about his shipmates dying in battle. Dialog started doubling up and then it suddenly closed. I tried re-creating the crash but was unable too, second playthrough went fine.
I was actually pretty interested in the possible mechanics of a navel battle game set on a board like this. I can see how the idea of advancing the story based on gameplay would have fit in nicely here. I don't believe I have any constructive criticisms that others have not shared, or that you're not already aware of.
Overall pretty good experience.
