Script

Sure! Here's a simple implementation of the popular game "Flappy Bird" using JavaScript and HTML. It includes pictograms and is designed for smartphone operation. Remember to save the code in a file with an HTML extension (e.g., `flappy_bird.html`) and open it in a web browser.

Please note that for the pictograms to be visible, you'll need to provide the URL of an image file (e.g., `emozi_all/bird.png`) for the bird's appearance. You can replace `'emozi_all/bird.png'` in the CSS section with the correct path to the image file. This implementation will allow you to play the Flappy Bird game on your smartphone by tapping/clicking the screen to make the bird jump and avoiding collisions with the pipes.
