Sure, I can help you with that! Here's an example of a decision-making game implemented as a single HTML file using JavaScript and pictograms:
Welcome to the Decision-making Game!
Assuming you are at a specific location and you need to make a decision.
Go to the Train Station
Go Shopping
Stay at Home
To play the game, you need to select one of the options: "Go to the Train Station", "Go Shopping", or "Stay at Home". Once you select an option, the game will display a result based on your choice.
Note: This is a simplified example. You can customize and expand the game based on your requirements.
