Sure! Here's a simple implementation of a Tower Defense game using JavaScript in a single HTML file:
To play the game, you need to save the code into an HTML file (e.g., `bloody_tower_defense.html`) and open it in a web browser. The game will start automatically, and you can control the player's position by clicking on the canvas. The objective is to prevent the enemies from reaching the player by placing towers using the mouse click. If an enemy collides with the player, the game will be over, and an alert will be shown.
Please note that this is just a basic implementation to give you an idea of how a Tower Defense game can be built. You can customize and expand upon this code to add more features and complexity to the game.
