Sure! Here's an example of a simple game room designed as a single HTML file using JavaScript and enclosed in script tags:
In this game room, there's a single pictogram displayed at the center of the screen. When you click on the pictogram, the `startGame()` function is triggered. You can write your game logic within the `startGame()` function to implement the actual game.
This is just a basic structure to get started. You can customize the game room as per your requirements and add more functionality using JavaScript.
