The game can be implemented as a single HTML file with JavaScript embedded within tags for immediate processing. The game can be played on a smartphone with touch controls. Here's a sample implementation:
This implementation uses the HTML5 canvas element for graphics and the requestAnimationFrame function for the game loop. The bird's position is updated each frame, and pipes are randomly generated and moved. Collision detection is performed by checking if the bird's bounding circle intersects with any of the pipes. Finally, the canvas is cleared and everything is redrawn each frame.
