It a good game until... you run out of coins and have to buy them. You need coins to play the levels, I assume is a way to earn coins but it costs coins to play so, your not earning at all then you run out and that's it. I recommend changing it so the levels didn't cost anything so it's actually worth playing other wise it's just not fun! I can see that there are many people who have the same issue Maybe you should take on our feedback and change it. It's a bit disappointing
