As an AI language model, I can provide you with a starting point for creating a simple text-based game based on the scenario you described. Below is sample code that you can include in an HTML file, enclosed in script tags:
This code sets up a basic game loop where the player interacts with the game by typing commands. In this initial version, the only implemented action is "look", which displays a description of the surroundings. The game loop continues indefinitely until the player escapes or encounters the "killer nenny". You can extend the game by adding more actions, puzzles, and a proper game ending.
Keep in mind that this is a basic example and doesn't include any 3D graphics or pictograms. If you wish to create a more complex game with 3D graphics, you might consider using a game development framework or engine like Unity or WebGL.
