Sure! Here's an example of a simple Super Mario game implemented as a single HTML file with JavaScript. Please note that this is just a basic implementation and doesn't have all the features of a complete game.
This implementation sets up a simple game loop where Mario continuously moves up while pressing the up arrow key or touching the screen on a mobile device. The goal is to collect the 5 gems by colliding with them. Once a gem is collected, a message is printed to the console.
Please note that this is just a basic example and can be further expanded and improved upon to make it a complete game.
