As an AI language model, I can provide you with a basic example of a text-based game implemented as a single HTML file using JavaScript.

This is a very basic game that simulates a simple banking system. You can play by opening this HTML file in a browser, and it will prompt you to perform either a deposit or a withdrawal. After the operation, it will show the updated balance and inform you whether you have been accepted into the bank or not.
