Sure! Here's a simple implementation of the classic game Flappy Bird in a single HTML file using JavaScript:
To run this game, save the code in a file with a `.html` extension, and replace the `src` paths in `bird.src`, `pipeNorth.src`, `pipeSouth.src`, and `background.src` with the paths to your respective image files.
This implementation of Flappy Bird uses the canvas element to draw the game elements, and JavaScript for game logic and event handling. When the game ends (bird collides with a pipe or canvas bottom), a game over message is displayed, and the page is reloaded to start a new game.
Keep in mind to replace the image paths with actual images in order to see the game elements. Also, note that this implementation does not include sound effects or touch-based controls for smartphone operation, but those functionalities can be added if desired.
