Sure! Here's an HTML file that implements the game based on your requirements:
This HTML file sets up a basic game framework with a canvas element for rendering and a JavaScript script tag for game logic. The game characters and their health are defined in the `characters` array. The `drawHealthBar()` function is responsible for drawing the health bars on the canvas. The `playGame()` function controls the game logic and updates the health bar accordingly.
Please note that this code provides a starting point for your game and doesn't include the full game logic, character interactions, or story mode. You will need to implement the remaining game features and functionalities based on your specific requirements.
