This game so far is the best I've tried,, compared to a game that's similar that I've tried, and find you can't continue if you run out of gems without having to pay for them,, making that dort of game really expensive to play,, so I just gave up on it,,, this game you can watch videos and get great rewards so please keep up the nice work, I've just finished ,even 7 of the first level,,, a long way to go yet,, but a good game thanks to the developers.
