Terrible design, when you run out of gems or energy after a round and start with zero in the next you cant do nothing. No back out button or explanation. And I'll tell you how I'm sure all people feel, IM NOT REPEAT IM NOT PAYING FOR ENERGY TO PLAY WHEN ITS INCLUDED WITH ALL OTHER GAMES! TIME TO GET YOUR HEADS OUT OF YOUR GREEDY KOREAN *****! REAL STUPIED MORONS!
