Sure, here's an example of a simple game called "Super Bitzees Games: Create Own Game To Play" implemented as a single HTML file using JavaScript:
In this example, the game implemented is a simple "Guess the Number" game. The player will be prompted to guess a number between 1 and 10, and they will continue guessing until they guess the correct number. After guessing the correct number, they will be congratulated.
Please note that this is just a simple example, and you can expand upon it and add your own game logic to create a more complex game as per your requirements.
