Script

Game Here is an example of a simple racing game implemented as a single HTML file with JavaScript. The game can be played on a smartphone by tapping the left or right side of the screen to move the car and avoid obstacles.

The game works by having the player control a car that must avoid obstacles that appear at the top of the screen. The car is controlled by tapping the left or right side of the screen, and the player scores points for every frame they survive without crashing. The game gets progressively harder as the speed of both the car and obstacles increases over time.
