Pathetic game. They have a puzzle you need to play to gain energy and after playing the puzzle I immediately leveled up. So guess what I should get energy points from the puzzle plus a full healh bar as per game rules. Well I didn't get the energy from puzzle. Well this is cheating and players are taken for a ride. Save yourself time there are plenty of good games out there. This is a trick to get people to spend more money. They even don't give what they promised.
