When I saw this in the app store, I thought this was an alright game. It had a fairly high rating, but I think that the developers must have gamed the rating system because anyone who has gotten passed the initial tutorial would be quickly bored by the tedious amount of grinding and the amount of in-app purchases that you get hammered with every time you want to do something.
The game has two different kinds of currency: One that proves pointless after 20 minutes and a true currency that you can only get by paying with real money.
Listen, if you're looking for a game that you only play once a day without paying $2-3, then this is it.
