Sure! Here's a simple mobile platformer game about Huggy implemented as a single HTML file using JavaScript and enclosed in script tags:
This game features a character named Huggy who can jump on screen touch/click. The game loop continuously updates and renders Huggy's position on the canvas. The player controls Huggy's jumps by clicking/tapping the jump button. The game also includes basic collision detection with the ground and prevents Huggy from falling below the screen.
Note: This is a basic implementation to get started with a mobile platformer game. You can enhance it further by adding platforms, enemies, scoring, and more game mechanics based on your requirements.
