Great art work – Zoo Craft: Build & Design Review

This is the best app ever! It is addicting and has few problems. One huge one is that animals can get out of their cage or pen. Another problem is that when I am playing the game, I find that I can not figure it out. I don't know how to work everything as soon as I get the app. That's preposterous. Anyway, the train is awesome! How do you get people on it?
