Gas, brake and balance
Hold Gas or the right arrow to drive, and Brake or the left arrow to slow down or back up; A and D work too, and so does holding either half of the road. The pedals also tip the jeep: gas lifts the nose and brake dips it. On the ground that gives you wheelies; in the air it turns the whole jeep, so use it to come down on both wheels.
Fuel, endings and points
The engine burns fuel all the time, and faster with a pedal down. Drive through a mango to fill the tank. A run ends when the driver's head touches the ground, the jeep gets stuck on its tail, side or roof, or the tank runs dry and the jeep rolls to a stop. You score a point for every metre, 50 for each full flip you land on your wheels, and 10 a second for any jump of over a second that you land on your wheels.
