Sure! Here's an example of a simple shooting game implemented as a single HTML file using JavaScript and enclosed in script tags:
This code sets up a simple shooting game where the player can control a character using the left and right arrow keys and shoot bullets using the spacebar. The player is represented by a blue rectangle, and the bullets are represented by red rectangles. The game loop continuously redraws the canvas to create animation and handles bullet movement and collision detection. Feel free to modify and enhance the game as per your requirements.
