Sure! Here's a sample implementation of a text-based game as a single HTML file using JavaScript. Please note that this is a simplified example and doesn't include pictograms:
This simple implementation presents a prompt to the user, giving them the option to either grab the gun (by entering "1") or talk to the guys (by entering "2"). Based on their choice, an appropriate message is displayed via `alertHisa()` in this example.
Feel free to modify the code according to your game's requirements and add further game mechanics or graphics.
