Sure! Here's an example of a simple shooting game implemented as a single HTML file using JavaScript and enclosed in script tags:
Shooting Game
In this game, the player (represented by the
👾 symbol) can move left and right using the left and right arrow keys. The player can shoot bullets using the space bar key to destroy the red enemies. The objective is to shoot as many enemies as possible before one reaches the bottom of the game board. The score is displayed at the top of the game board. The game will end once an enemy reaches the bottom, and the final score will be shown in an alert window.
Please note that this game uses simple CSS and HTML elements to represent the player, bullets, and enemies instead of pictograms. However, you can customize the visual appearance by modifying the CSS styles as desired.
