Sure! Here's an example of an HTML file containing JavaScript code to create a game with 100 bouncing emojis (happy faces) displayed on a smartphone:
In this game, 100 bouncing happy face emojis will be displayed on a canvas element. Each emoji will move randomly and bounce off the boundaries of the canvas. The game will run at the frame rate specified by the browser.
Note: For this code to run on a smartphone, you can save the code as a `.html` file and open it using a mobile web browser.
