I ran out of energy during the game, and was feeling stupidly competitive, and I was also out of crystals. I have played this game for over a year now, and I have NEVER bought crystals with real money...till now. It was so stupid. I really can't afford to buy things like this.

After I bought crystals...the icon where you get 10 free crystals a day by watching videos disappeared and I suspect that it will not come back because I BOUGHT crystals. Does anyone know if the free crystals have disappeared forever?
