Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript and enclosed in script tags:
In this example, we have a game framework set up with a canvas element for drawing, a player position, and an image for the player. The initialization function sets up the canvas and loads the player image. The draw function is the game loop that clears the canvas, draws the player image, and handles game logic. The handleTouch function handles touch events to control the player's position. You can extend this code with additional game logic, level design, and more to create a complete game experience.
