Sure, here's an example of a text-based game written in a single HTML file using JavaScript. In this game, the player controls three characters: Hot Meowscarada, Lopunny, and Glaceon. The objective is to help them work together to find their way back home after falling off a mountain.
Please note that this is a basic text-based implementation without any graphical elements or pictograms. It can be played by entering character indices and distances to move through the prompts in the browser's console. You may need to open the browser's developer tools (usually by pressing F12) and switch to the console tab to see the prompts and game progress.
Feel free to customize and enhance the game by adding more features, visuals, or interactivity based on your requirements.
