5 stars for a great game. 1 star for the cost of add ons. The paywall hits pretty hard at level 40 and the $50 to purchase the last two crafters is a little excessive. I don't mind spending money on a game but I feel the developers of this app are a little greedy in the price of the additional crafters. When you consider you can't save up premium in game currency to buy the crafters, that you have to spend $50 to get them it seems a bit much. Aside from that the game itself is quite fun.
