Diamonds will appear randomly on the streets. When you collide with an obstacle, you can spend a diamond to continue.
Double jump
The double jump is very useful. Use it when an initial jump ends up short.
Power ups
The following power-ups are available.
Golden bike: Increases your speed, become invincible, and attracts nearby coins.
Golden headphones: Briefly stops cars.
Golden shoes: Move slightly faster.
Because the prices for new characters and bikes are steep, save coins to upgrade your power-ups instead.
Wheelies
Swipe down to perform a wheelie. The wheelie meter will appear at the top left corner. To remain in the wheelie, rapidly swipe down while avoiding obstacles. Jumping will immediately end the wheelie. Completing a full wheelie by allowing the meter to run out will result in 100 coins.
