Sure! Here's an example implementation of a game similar to Mario, using JavaScript and HTML with smartphone-friendly controls:
In this example, we have a simple game canvas represented by a div with the id "gameCanvas". The player object is a red square represented by a div with the id "player". The player can be moved using the arrow keys on a keyboard or arrow buttons on a smartphone screen.
You can further extend this game by adding platform elements, enemies, collectibles, levels, and more. But this basic implementation should give you a starting point for a simple Mario-like platformer game.
