Sure! Here's a simple game implemented as a single HTML file, using JavaScript and enclosed in script tags:
This game sets up a canvas where you can control a red square (representing Super Man) using arrow keys on your smartphone. The square moves horizontally and vertically within the bounds of the screen. By using JavaScript, the player's movement is handled and the canvas is updated at 60 frames per second.
Please note that this is a basic game implementation and can be expanded upon with additional features, levels, or graphics based on your requirements.
