Beach Resort Escape

You are in the beautiful island with your friends. You are having a nice vacation there. The view is awesome and you are having so much fun with your friends. Now your vacation is over, it is sad, but you need to go back home now. The ship that carried you in that island already left and your friends were on that ship. You are left on the island and you have to find a way to escape. Got an idea? Good Luck!
