Sure! Here's an example implementation of a simple tower defense game using HTML and JavaScript:
You can copy and paste the above code into a single HTML file to play the tower defense game. When you open the HTML file in a web browser, it will display a canvas where you can place towers on the slots to defend against enemy attackers. The game will start automatically, and you need to strategically place towers using the available mana to defeat the enemies each wave. The game will continue until all slots are filled or your territories are overrun by the enemies. Good luck!
