l love the concept of this game and have fun when the levels are challenging but not insanely hard. Most of the time the ONLY way to complete some levels is by buying coins to buy boosters. I'd rather watch an ad to get a booster. Most games you play offer a daily gift. This game has tremendous potential but until they start offering something that doesn't always require money, I'm not interested.

stuck with no option than purchase. level 172, no coins, no power ups cant solve and the only way to get past is with a purchase. the game has become unplayable so will be uninstalling. also for hard levels you get the same amount of Coins for easy levels which also sucks since everything cost so much and you have to watch an add after ever round and hopefully play 12 -15 rounds just to refill a power up. absolutely fun otherwise but the rest if it is a complete turn off.

I love this game! It's very addictive and oddly satisfying. My one problem with the game is the spacing of the hard levels. There's a "hard level" every three or four levels, and once there were three hard levels in a row! I think there should only be one every ten or fifteen levels. Also I feel like there are some levels you can't win without using coins, and sometimes that involves paying real money. Other than that, I love it!
