I built a pretty large zoo with a bunch of animals and shops. The variety of animals was amazing and I loved how they moved around. I met all the needs of the animals but it was unclear what would happen if I didn't. I'm pretty sure the people got happier the more stuff I put in so thats what I did, but is there a deeper layer to this? Do visitors want to see certain animals? I thought the feature to change the color was good and worked for me well. Are you gonna add more to the game? Good job with this one, your collection of games grows to an impressive amount!
