Sure! Here's a basic implementation of a third-person shooter game using JavaScript and HTML:
This game creates a simple third-person shooter where the player controls a blue box using the mouse. The enemy, represented by a red box, moves towards the player. The goal is to avoid colliding with the enemy. If a collision occurs, a "Game Over!" message is displayed.
Note that this is just a basic example to get started. You can enhance and customize this game further based on your specific requirements, such as adding multiple levels, different skins, and gameplay mechanics.
