I used to love this game, but now have no desire to continue. Since the Captains were changed to Admirals, the game is basically worthless. There are no instructions on how to use the Admirals, or how or why to upgrade them. They mean nothing to the game. I am up to level 794, but that means nothing now, too. I have plenty of money, jewels, ships, etc. but am stuck unable to use anything because of the upgrades required but unavailable. Even minimal upgrades take a week or better to finish.
