Script

This is a simple car drifting game implemented in a single HTML file. The game is controlled using the arrow keys on a smartphone. The player must steer the car down a winding road while drifting and avoiding obstacles. The car is subject to gravity and will accelerate downward as it gains speed. The game is won by reaching the end of the course without crashing. The graphics are simple but effective, using an image of a car that rotates left and right based on the player's input. Enjoy the ride!
