This game looks good, is fun, and difficult. The graphics and the animations are well done. Coins are easy to come by, but gems are not, without $$, I have no lag or crashing issues that others are complaining about. Im running it on an iPhone 6 with the latest iOS.
Update July 2016:
I quit playing this game for months and then re-downloaded it. What happened to this game? You finish levels in the middle of a run? The game seems to run slower, and it seems as if there are less coins. The addition of the little progress map seems silly. Disappointing update, whenever it occurred.
