Certainly! Here's an example of a simple implementation of the classic game Super Mario Bros using JavaScript and HTML:
This code sets up a simple game canvas and allows the player to control a red square using arrow keys on a smartphone. The player moves with the arrow keys, and the screen is refreshed every frame to show the updated player position.
Note that this is just a basic starting point, and you can enhance it further to add sprites, levels, enemies, and more game mechanics to create a complete Super Mario Bros experience.
