Oh man, I replayed thinking that if I only sold captives w/o ever ransoming anyone it would give me a different ending. I believed it was implied sinse the option to gain less money by doing so was there. Oh well, it's okey.
Another minor criticism is that the ending is a little unclear: Does the Sea Goddess get sealed and controlled like a puppet? Does she only get sealed while Mrs. Captain controls her powers? Or what happened?
Again, great game.
