You can add more animals like chickens, pigs, cows, various types of fish, and terrain types like desert, snow, and lunar land.

I'm planning to make a 4x game with your assets, however, it's missing quite a few things.
 Currently, I'm using AI to fill in the missing assets. If you could draw them to compensate, I would be very grateful. I'm willing to pay for an expanded set of assets.

Thanks for the suggestions! 😊 I do plan to add more animal variations and a few different terrain types in future updates.
