Sure! Here's an example of a simplified Flappy Bird game implemented as a single HTML file:
This implementation of Flappy Bird uses HTML, CSS, and JavaScript to create a game where the player taps/clicks to keep the bird flying and avoid collisions with the pipes. The score is displayed in the top-left corner, and the game ends when the bird collides with a pipe or touches the ground.
Please note that this is a simplified version and may not include all the features of the original Flappy Bird game.
