Sure! Here's a simple RPG game implemented as a single HTML file using JavaScript:
To play the game:
1. Copy the above code and save it as an HTML file (e.g., `rpg.html`).
2. Open the saved HTML file in any modern web browser.
3. You will be prompted to enter your name for the game.
4. The game will display messages in the console with the battle progress.
5. The game will end when either the player or enemy health reaches 0.
Unfortunately, I cannot provide pictograms in this text-based response. However, you can customize and enhance the game by adding ASCII art or images to represent the characters and battles.
