Sure, I can provide you with a simple example of a text-based adventure game designed to run in a web browser. This implementation won't have graphics or pictograms but will still allow you to explore an imaginary world, interact with objects, and engage in combat.
Here's an example of how the code structure can look like in a single HTML file:
Please note that building a full-fledged 3D adventure game like "The Legend of Zelda" can be a complex and time-consuming task, requiring extensive knowledge of game development concepts, programming languages, libraries, and tools. This example serves as a starting point for you to get an idea of the structure and flow of a game but will require significant effort to develop into a complete game.
I hope this helps you in your game development journey!
