Sure, here's an example of a simplified version of the Flappy Bird game implemented as a single HTML file using JavaScript:
To use this, save the above code into an HTML file (e.g., `flappyBird.html`), and save an image named `emozi_all/bird.png` in the same directory as the HTML file. Then, you can open the HTML file in a web browser on your smartphone to play the Flappy Bird game.
