Sure! Here's a simple example of a billiards game with enemies implemented as a single HTML file using JavaScript:
This game represents a billiards table (`#board`) with a player (`#player`) and two enemies (`div class="enemy"`). The player can be moved using the arrow keys. The enemies are stationary in this example, but you can update their positions randomly or based on specific logic.
Please note that this is a basic example and does not include all the mechanics of a traditional billiards game. It serves as a starting point for you to build upon and add your desired functionalities.
