Decent game at first but definitely gets way to expensive to play. The exchange rate it way to low. After getting to level 324 after spending a ton of money on diamonds to upgrade things I now keep getting a "parsing error" and can not go any further. If they make the diamond exchange rate cheaper it is worth a week or two of playing but if you don't have money to play you are just going to end up waiting to play for days until things finish upgrading.
