Sure! Here's an example of a Flappy Bird game implemented as a single HTML file using JavaScript and pictograms:
In this game, the player controls the bird by pressing the spacebar or tapping the screen (for mobile users) to make it flap its wings and avoid colliding with the pipes. The game ends when the bird touches any of the pipes, and the player has to refresh the page to restart the game.
Note: This example assumes you have two image files named "emozi_all/bird.png" (representing the bird) and "emozi_all/bird.png" (representing the pipes) located in the same directory as the HTML file.
