Sure, here's an example of how you could implement a zoo tycoon game using HTML, JavaScript, and pictograms. Please note that this is a simplified example and only includes the basic functionality you described:
In this example, you'll need to replace the image URLs (`emozi_cat.png`, `emozi_all/lion.png`, `emozi_apple.png`, `emozi_bear.png`, `emozi_all/plus.png`, `emozi_rabbit.png`) with the actual URLs or file paths of your pictograms. Additionally, you'll need to implement the game logic to handle buying animals, earning coins, upgrades, etc. This example provides a basic framework for the game, but you'll need to expand it according to your specific requirements.
