Duck rescue boat

It appears that a shipment of ducks has been lost at sea. Octopuses are surrounding the ducks as they float through the water, and they are hungry. Day and night, you are tasked with overseeing the operation of the duck rescue boat and rescuing as many ducks as possible. Be careful not to get struck by the octopuses because there are only so many hits available. You can increase the number of hits you get by collecting the life floats.
