To test the game, you can copy this code into an HTML file and open it in a web browser on your smartphone. Make sure to place images of the arrow pictograms in a directory named "images" relative to the HTML file (e.g., `emozi_all/game.png`, `emozi_cat.png`, etc.). The game should start immediately, and you can press the arrow keys to play.
