Score: 0
To play the game, simply save the code into a file with a .html extension (e.g., flappy_bird.html) and open it in a web browser. Then, click on the screen to make the bird jump and avoid colliding with the pipes. The score will increment each time the pipes are passed. If the bird collides with a pipe, the game will end and a score will be displayed.
