Sure, here's an example of a game called "Fly Swap" implemented as a single HTML file using JavaScript and enclosed in script tags:
To play the game:
1. Save the above code as an HTML file (e.g., "fly_swap.html").
2. Save the provided images (fly.png and swatter.png) in the same directory as the HTML file.
3. Open the HTML file in a web browser, preferably on a smartphone.
4. Click on the canvas to move the swatter and try to catch the fly.
5. Each time you catch the fly, your score will increase, and the fly will reset its position.
Note: Make sure to replace "emozi_all/fly.png" and "emozi_apple.png" in the code with the actual paths to the respective image files you have.
