Here's an example of a simple Life Simulator game implemented as a single HTML file using JavaScript:
In this game, you can use the plus button to age up, which will increase your age and earn you coins based on your age. The "simulateLife()" function is responsible for simulating life events, displaying them, and asking questions related to each event. You can also check your relationships with people by calling the "checkRelationships()" function.
This is just a basic implementation to get you started. You can further enhance the game by adding more events, customizing the questions, and implementing additional features as per your requirements.
