The game is very fun and well made. The merges are interesting and there are always new items and side events that keep me engaged with the game. I don’t regret downloading it.
The only real downside is the most common one that affects most games I own: the in-game currencies. Energy is used up quickly and the only ways to get more other are waiting for it to recharge, watching videos every two minutes, or spending real money. I’m not spending real money on game currency, so when I get tired of ads, I just quit the game and come back to it later. Most things that don’t cost real money use diamonds, which are earned very slowly and can be spent very quickly. Game coins are easy to earn, but there isn’t much you can do with them as few things can be bought with coins. I have nearly 3000 game coins now, and nothing much to spend them on. So, anyway, the ratios of currency and energy are quite irritating and reduce game play for me.
However, this is a common game problem with iPad games! Most game developers seem to think that if they make the game currency ratios as annoying as possible, that they will somehow seduce me to use real money to buy more of the in-game currency. Sorry, not happening! I have better things to spend my real money on. All your annoying ratios do is to make me play your game less than I otherwise would!
Apart from the currency annoyances, it’s a great game and I really enjoy playing it.
