Sure! Here's a simplified version of Flappy Bird implemented as a single HTML file using JavaScript:
In the above code, you may need to replace the `emozi_all/bird.png` and `emozi_chicken.png` URLs with the actual paths to the pictogram images you want to use.
To play the game, you can open the HTML file in a web browser (preferably on a smartphone). The bird starts falling automatically, and you need to tap the screen to make it jump. The game ends if the bird touches the ground or hits the pipes.
