Sure! Here's a simple implementation of a city growing game using JavaScript and HTML:
This game features a canvas element that displays the statistics of the city, including population, number of buildings, and available money. The city will continue to grow automatically even when the player is not actively playing the game. The growth occurs at random intervals and increases the population, number of buildings, and available money.
Note: This is a basic implementation just to give you an idea. You can enhance it further by adding more features, interaction, graphical elements, and better visual representation.
