As an AI language model, I can provide you with a basic example of how you could structure a simple game using HTML and JavaScript, inspired by Super Mario RPG. Please note that this is just a starting point and not a complete or fully functional game.
In this example, when loaded in a web browser, it creates a canvas element and listens for keyboard events to move a Mario pictogram around the screen. You would need to provide an actual pictogram image (such as `emozi_all/keyboard.png`) for this to work correctly.
This is a very basic example to demonstrate the structure of a game using HTML and JavaScript. To create a fully functional Super Mario RPG 2 game would require much more complex code, graphics, and game mechanics.
