Absolutely no help or instructions. Terribly confusing reward system with hearts, gems, coins, etc. No free play option after a couple of days, at which point it gets very expensive. Absolutely hate the distracting exaggerated facial expressions on the stones with no option to turn it off. I think it's one of the better learning apps out there, but the team clearly needs someone with some business sense.
Very confusing. Poor English, strange options. I wanted to learn and practice, but have to go through a confusing set of tutorials first. No thanks.
Incredibly expensive! Better get another app!
It teach step by step with emotion icon. Great! But it needs is to buy diamond to continue.
Tutorial does not explain how to play very well!
Ugly and donate greedy
Improved Game System.
