Sure! Here's a simple implementation of a civilization builder game called "Civil1". This game allows you to make decisions and progress through different eras starting from caveman times and continuing until the end of the solar system. The game is designed for smartphone operation and uses pictograms to represent various elements.
When you execute this HTML file in a web browser (preferably on a smartphone), it will start the game in the caveman era. You will be prompted to make decisions based on the era you are in. As you make decisions, you will advance to the next era until you reach the end of the solar system era. The implemented game logic is basic, but you can expand it further according to your preferences and requirements.
