The Harbor

Your mission is to take the containers from the trucks into both ships.
Move the crane left or right using the arrows keys, take or drop a container using the center button.
When a ship holds more than five containers it might leave the port, but only when the ship is full you'll get full points.
Beware not to drop any container on the road or into the ocean.
Take the container from the truck before the next truck might crash into the waiting truck.
