Sure! Here's an example of a simple chatbot game implemented in a single HTML file using JavaScript:
In this chatbot game, the chatbot will prompt the user to enter their message. The game progresses based on the user's input. Initially, the user needs to type "play" to start the game. Once the game is finished, the user will be informed and the game will not continue.
Please note that this is a very basic example game, and you can customize and expand the logic according to your game requirements.
