The aim of this game is to
control the traffic lights so that as many cars as possible can
pass from one side of the screen to the other. Traffic lights
can be changed by clicking on the junctions. Every time a car
passes across the city you score 1 point. As your score
increases the amount of cars entering the city will increase.
The amount of cars queuing outside the city is shown in the
queue scorebox. If 5 or more cars are queuing outside the city
then its game over!
