Sure! Here's a simple airplane shooting game implemented in a single HTML file using JavaScript and enclosed within script tags:
In this game, you control a player's plane at the bottom of the screen using touch input. The objective is to shoot down the enemy planes by tapping on the screen. Your score increases each time you successfully shoot down an enemy. The game loop runs every 10 milliseconds to update the game state and redraw the canvas.
Note: This is a basic demonstration of a plane fighting game and can be further enhanced with additional features, graphics, sound effects, and more.
