Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript. The game is played on a smartphone and the objective is to eat an egg to win:
To run this game, save the code in a file with a .html extension (e.g., `game.html`), and place an image of an egg called `emozi_all/game.png` in the same directory as the HTML file. Open the HTML file using a web browser on your smartphone, and you should be able to play the game by tapping on the egg pictogram. If you eat an egg, the game will display a congratulatory alert.
