The player car moves in a circle (loop)
The player can control the car by moving it either clockwise or counterclockwise (There is a toggle button for this purpose).
The player can adjust the speed of the car, so he can control the car easily.
The Player has an alternate vehicle (a truck). Which can be activated by keeping the right-hand side button pressed.
The player can approach the Bonus cars comparatively easily, with Truck mode. But trucks' life is lesser than cars.
Either (car or truck) of death, will end the game.
The Player's car has to face three types of cars. Enemy Cars, Bonus Cars, and Mysterious Cars.
The Player has to avoid Enemy Cars. Otherwise, player health will be suffered.
The Player has to hit/collect Bonus cars. Bonus cars either heal the player or give the points.
Mysterious Cars can be either Enemy or Bonus cars.
