Sure! Here's an example of a simple football game implemented as an HTML file:
This game creates a simple football-like experience where you control a player using the left and right arrow keys on your smartphone. The objective is to keep the ball bouncing by using your player to hit it. The ball and player are represented by simple shapes (circles and rectangles) on a HTML canvas.
To play the game, you can copy and paste the above code into a single HTML file and open it in a web browser on your smartphone. The game starts automatically, and you can control the player's movement by tapping the left or right side of the screen.
