Sure! Here's a simple implementation of the Flappy Bird game in a single HTML file using JavaScript:
To use this code, you need to save it as an HTML file (e.g., `flappybird.html`) and also have an image file named `emozi_all/bird.png` in the same directory as the HTML file.
You can open the HTML file in a web browser, and you should be able to play the Flappy Bird game. Click on the canvas to make the bird jump and avoid the green pipes. If the bird collides with a pipe or touches the ground, the game will end and display a "Game Over" message.
Please note that this is a very basic implementation and may not have all the features and polish of the original Flappy Bird game. However, it should give you a good starting point.
