Once you have saved the code as an HTML file, open it in a web browser on your smartphone. The game will display a red "hotdog" that moves around the screen. Use the arrow keys to control its movement. The score will be displayed at the top left corner of the screen. The objective of the game is to navigate the hotdog to avoid hitting the walls of the canvas.
