Sure! Here is a simple implementation of Flappy Bird as a single HTML file using JavaScript:
To make it work as a game, you need to save this code as an HTML file (e.g., `flappy_bird.html`), and make sure to create or find suitable pictogram images for the bird and pipes. Save those images as `emozi_all/game.png` and `emozi_apple.png` in the same directory as the HTML file.
To play, simply open the HTML file in a web browser, and you can control the bird's movement by clicking on the screen. The objective is to navigate the bird through the gaps between the pipes without touching them. Your score will increase for each pipe successfully passed. If you collide with a pipe, the game will end and display a "Game Over" message.
