You need to buy everything. It's very far different from the advertise. I don't like it, so I'll give it a 1 star. And everything is so hard and you had to buy everything, the walls, and the other good stuff. Or else your just left with the bad ones. And oh my gosh the ads, the ads are too many. They popup any second I click something, Ugh. Money hungry much? Don't reccomend this game to y'all, it's very far from the advertise.
