Updated. Now they have made a new change that just made progression that much harder...at the rate of coins earned and and cost to upgrade...will take me about 10months to get 1 char from 17 to 18. Worse for lower levels. Unless I pay money. Here's the kicker if I spend money they charge me significantly more than people who rarely spend money. Sometimes $50 to $60 difference in price. I like the game but if thinking about starting, find another game. Wildlife Studios only wants your money!
