Sound
Volume levels of the music and sounds can be controlled via the Options → Sound page.
All volume levels are relative to your devices volume settings. If you simply wish all volume levels to be raised or lowered you should use your devices volume control. If you wish to fine tune relative volume levels between music and sound effects then you can use the sound control page.
Music controls the volume of the music that plays whilst navigating menus.
Ship Noise controls volume of your Jet Racers engine whilst in game play.
Sound FX controls the volume of all other sound effects whilst in game play, such as weapon firing, shield activation and explosions.
Vibration
If you are playing TJR on a device with vibration available use this to control the vibration of the device when your racer collides with objects or is hit by weapon fire.
