I deleted this app from my phone today after getting to level 480. Such a shame. The game itself used to be fun but the levels become so hard, you are required to use coins for help or you can't pass the level. The cost of those "assists" keep going up. This is becoming the most expensive game I've ever played. Playing just became frustrating and not enjoyable. If you're going to download this app, just be prepared to delete it after a short time or spend a bunch of money.
