Average, needs improvement
Its an interesting concept, another get as far as you can sort of game.
Zero explanations though, and the pacing is very slow (earn gold slowly) and not very many options for rewards.
As nifty as this is, it needs to learn how to reward its players, not just the ones that buy IAP.
Space out the rewards, make some available right after a few plays, not set the bar after a hundred plays to earn enough to buy one thing that doesnt do anything.
Dont fall into the IAP way of things, that just makes for crappy games.
