Sure! Here's a simple football game implemented as a single HTML file using JavaScript and enclosed within script tags:
In this game, you'll see a canvas with a football image moving around. The football will bounce off the edges of the canvas.
To play the game, save the above code in a file with a `.html` extension, and also save an image of a football as `emozi_all/play.png` in the same directory as the html file. Then, you can open the html file in a web browser and the football game will start automatically.
Feel free to customize the game further by adding more game logic, scoring, controls, or additional graphical elements as per your requirements.
