Sure, here's a basic example of a football game based on the Qatar World Cup 2022. Please note that this example is simplified and doesn't include graphics or advanced gameplay mechanics. It uses JavaScript and is contained within `` tags in a single HTML file.

<style>
canvas {
border: 1px solid black;
}
</style>
<canvas id="gameCanvas" width="500" height="300"></canvas>
This code sets up a simple football game where you control a player using the up and down arrow keys. The objective is to prevent the ball from hitting the goal post represented by the right wall of the canvas. You can enhance the game by adding goal scoring mechanics, opponent players, and better graphics, but I hope this example gives you a starting point. Good luck with your game development!
