The game is okayish. But if you have downloaded this from Tapjoy to earn some credits, don't bother, Tapjoy will not pay up. Their reply to me for refusing to honour : After reviewing the data in our system, we were able to confirm that the app install is not attributed to Tapjoy. This might happen for several possible reasons like not having the app opened for at least 10 minutes after the install or an interruption during the download.
