I absolutely hate your piggy bank system, it's such an injustice... That we have to buy gems to open the piggy bank, that we have so hard to fill... I bet if you don't have the gem cost to open the piggy bank, you would make more money in the end...just the resentment factor alone takes away from the enjoyment of the game....it leaves such a bad taste in the mouth...a feeling that "I will never spend a penny of real money ever" ever on your game until you remove this system.
