Not Zen-Like At All. Super stressful and can be difficult. The rewards do not outweigh the costs to play. Oftentimes, I have to spend 30 to 100 coins to complete the level, and I only get 10-20 coins reward. I am spending far too much money just to stay in play. Please increase the rewards! Raise the rewards to give us a fair chance to keep playing. I have spent over $50 in less than a week and had to give up. It's ridiculous. Please make the rewards at least 10 times higher!
