I've recently started playing this game on Facebook and it's pretty simple but nice as well. You're basically owning a piece of land/jungle where you can build stuff and animals to gain in levels. You'll also need to do quests to gain more silver to buy all the animals and stuff.
You also need "neighbors" to occassionally help you build stuff. Anyone else playing this game on Facebook and want to add me as your friend/neighbor? Please do so, I could really use some help building a habitat for my sweet little lions...
