As an AI text-based model, I can provide you with an example of how you could create a simplified version of Super Mario 64 (SM64) as a mobile game using HTML, CSS, and JavaScript. Since creating a full port of SM64 would be a significant undertaking and not feasible within the context of a single HTML file, the example below will demonstrate a basic game inspired by SM64. This example will use simple pictograms and a minimalistic design.
In this example, pressing the Space key will make the player jump. The player is represented by a red rectangle. Gravity pulls the player downward, and collision detection prevents the player from falling through the bottom of the canvas.
Please note that this game is a simplified version inspired by Super Mario 64 and does not provide the full gameplay experience. It serves as a starting point to build upon.
