Have this piggy bank thing which eats up all the diamonds. I think at stage 3 of each level, we were supposed to get 5 diamonds, but coz of the piggy bank, the diamonds went into the piggy bank and they make us pay with real life money to get the diamonds out from the piggy bank. Filled with alot of ads, I actually paid for the ads free coz I was having fun and the game's ad was super long.
