Follow the arrows on the asphalt until you reach the parking place, where you'll have to park the bus as it is indicated...lead and accelerate with the arrows of the keyboard, and slow down with the spacebar
You gotta drive a load truck, pick up the stuff at the beggining and deliver it at the end. Careful! Don't lose anything on your way and don't dump the truck. Use the arrows.
Go through all the possible distance before your car runs without fuel. Press the space bar to jump and use the arrow keys to balance your vehicle. If you don't hit anything you will gain speed with your car.
