Sure! Here's a simplified version of Flappy Bird implemented as a single HTML file using JavaScript:
When you open the HTML file in a web browser, you will see a canvas representing the game screen. The objective is to keep the bird flying by tapping the screen. The bird needs to avoid colliding with the ground and pipes. The score increases as the bird passes through the pipes. The game ends when the bird hits an obstacle.
Note: This implementation is a simplified version of Flappy Bird and may not include all the features of the original game.
