I would give zero stars of I could. The game tries to encourage you to spend money to get you through levels. Even if I won the lottery, I wouldn't spend a penny on any purchases. More than likely, I would create a million accounts to bring the rating down. I play this and Toy Blast, without any purchases, and I'm over 700 levels further. When you get free time limits, it's usually all at once. Dragging on the agony, and I usually quit because I don't have the time to play for an hour.
