I had to change my review from 5-3 star as I have to spend a fortune just to pass most levels. I paid $8 for the game for last month and played every day and spend more money but still ended up around level 24 out of 30. The pink levels are impossible to beat without extra booster/coins and u end up losing all of yr booster after losing the pink round. Since this afternoon, every time I open the game and click yes, the game shuts down, u have a bug in the system, couldn't finish my $8 game.
