We’ve got two pedals, the right one is the Gas and the left one is your Brake. 
The Gas pedal will accelerate your truck and the Brake will stop and reverse you. The pedals will also control your trucks tilting direction if you manage to catch some air off a jump, using our patented invisible tilt ninjas, helping you to get the right balance and landing. You can invert the tilt direction under the Settings menu in game.
