Script

Sure! Here's a simple shooting game implemented as a single HTML file:

This game features a simple shooting mechanic where the player can move horizontally using the left and right arrow keys and shoot bullets by pressing the spacebar. The goal is to shoot down the enemies before they reach the bottom of the screen. If an enemy collides with the player, the game is over. The game is enclosed in the script tags and implemented using the HTML5 canvas element along with JavaScript for game logic and rendering. Pictograms can be added to the game by replacing the player and enemy shapes with image assets.
