During the stone age, life is pretty advance than most people would have think of it today. They have car, houses and a lot more. But, what they lack that time was parking lots, so it is pretty obvious that they have a traffic all the time since the cars are parked everywhere.
Drive your car to the parking spot without hitting anything. That means dinosaurs, car, man, and even those that are not moving. The game has a time limit and you need to get to the parking area before time expires. The game gets even more harder as you progress in the game.
