Sure! Here's a simple implementation of the Flappy Bird game in a single HTML file using JavaScript:

To play the game, open the HTML file in a web browser on your smartphone. Tap/click on the screen to make the bird jump and avoid obstacles. If the bird hits the top or bottom edges of the canvas, the game ends, and an alert displays the "Game Over!" message. To play again, you can simply reload the page.
