Your task is to drive a ferry boat around marina, to search for the treasure boxes and to load in the required amount to complete the level. You will find the treasure boxes usually somewhere around the dock. Level 1 requires only two such boxes to collect. If you hit other boats, rocks sticking out of the water surface, dock or any other obstacle, your health meter goes down, so you should closely watch it. To improve the boat's health, i.e. to repair it, you can pick up the wrench tool icon floating in the water. There is no map, so you can't see where are the rest of the boxes hidden, but once you find them all, a little yellow arrow will guide you to the warehouse where you can unload the cargo.
