Script

Sure! Here's an example of a side-scrolling platforming game implemented as a single HTML file, using JavaScript and enclosed in script tags:

This simple game defines a player character represented by a red rectangle, and platforms represented by blue rectangles. The player can move left and right using arrow keys and jump using the up arrow key. The game checks for collision between the player and platforms to handle jumping and landing mechanics. Please note that this is a very basic example and can be enhanced further with additional features, levels, animations, and graphics, depending on the complexity you desire for your game.
