Sure! Here's a sample implementation of a pet rock game using HTML and JavaScript:
In this game, the pet rock is represented by the `petRock` object. It has properties for hunger, bladder, happiness, tricks, and friends.
You can interact with the pet rock by calling its methods like `feed()`, `bathroom()`, `pet()`, `playBall()`, etc. These methods will update the pet rock's needs and happiness accordingly.
The `gameLoop()` function acts as the main game loop and it updates the pet rock's needs and happiness every 5 seconds.
Remember that this is just a basic implementation to give you an idea of how the game could work. You can expand upon it and add more features, interactions, and visual representation using JavaScript frameworks and libraries.
