Here's a sample implementation of a Flappy Bird game using HTML, CSS, and JavaScript. It is designed to be played on a smartphone and uses touch screen controls.
Score: 0
To use this code:
1. Save the code in an HTML file (e.g., `flappybird.html`).
2. Save an image of a bird as `emozi_all/bird.png` in the same directory as the HTML file.
3. Open the HTML file in a web browser on your smartphone.
4. Start playing the Flappy Bird game by tapping on the screen to make the bird flap and avoid the green pipes.
5. The game will continue until the bird collides with a pipe or hits the top or bottom of the screen.
6. After the game ends, an alert will display your final score.
Note: This is a simplified version of Flappy Bird and may not have all the features of the original game.
