You are driving a helicopter and you must avoid to collide with the mountain and the penguins. The primary advantage of a helicopter is from the rotor which provides lift without the aircraft needing to move forward, allowing the helicopter take off and land vertically without a runway. For this reason, helicopters are often used in congested or isolated areas where fixed-wing aircraft cannot take off or land. The lift from the rotor also allows the helicopter to hover in one area and more efficiently than other forms of vertical takeoff and landing (VTOL) aircraft, allowing it to accomplish tasks that fixed-wing aircraft cannot perform.
