Sure! Here's an example of a simple parkour game where you jump over rocks. It's implemented as a single HTML file, enclosed in `` tags, and written in a functional program:
<br><br>
<br>
<style>
canvas {
border: 1px solid black;
}
</style>
<canvas id="gameCanvas" width="400" height="300"></canvas>
To run the game, you can simply copy and save the code in a file with a .html extension (e.g., `parkour_game.html`), and open it with a web browser. You'll see a canvas where you can control the player using the spacebar to jump over rocks. If the player collides with a rock, a game over message will appear, and you can restart the game by reloading the page.
