The game is a simple ice cream maker as we've seen a few times before. The difference is that this game has no upgrades or anything you can work towards, except for a highscore. It gets boring after two levels.
If you click on retreat before it is your turn, you will retreat at the end of the enemy's turn. When buying upgrades, you don't have to buy the weaker upgrade first. Go for the war ships, fighting earns enough money to pay for cannon balls. Destroying ships earns just as much as boarding them. If you click on the map button before finishing salvaging, you don't get any money or cargo.
Looks pretty good. Would be neat if there was content. Maybe things you could unlock with points you gain by collecting stuff or doing stunts. More terrain types would be nice as well.
