★★★ Great game, one problem. So I have played this game for years, and never had a problem with it……until they added demons, so you see here this is a problem fpr me because im no longer allowed to play it, because of the demons, and this is a alien game so i dont understand, but besides that gameplay is great, and fun to play
★★ Find something else I have put a lot of time into this game. The unrelenting pop ups are obnoxious, quest rewards make no sense, it becomes overwhelming with the amount of materials you have to grind. Seriously you are better off playing a match three game.
Money Grab Huge money grab, peppered with ads, constant micro transactions in your face, and to get rid of ads, you have to pay a subscription.
