Sure! Here's a simple Star Wars Tower Defense game implemented as a single HTML file using JavaScript:
This game sets up a tower defense scenario where the player can place towers on the game screen by clicking, and enemies will move from right to left. The goal is to stop the enemies from reaching the left side of the screen. If an enemy reaches the left side, the game is over. It's a basic implementation but you can add more features, levels, and complexities to make it more interesting. Hope you enjoy it!
