The Pirates Time 2 level pack includes 15 new levels of pirate cannon shooting fun.  But you also need to have some good aim and a good strategy if you want to make to the harder later levels.  You will be on your Pirate ship out in the ocean but the bad guys are on land and hiding behind some obstacles that you will have to blast through if you want to shoot them.  So make sure your aim is good, let your cannonball fly and take out the bad guys.
