The longer you play the harder it gets to complete the levels and earn stars (no news there). But after a while it gets pretty boring - you use stars to finish and start each day,for the idiotic main character to talk to others, go to the mailbox... come on! Truth be told they are not as greedy as other developers, since you can get some boosters and coins for free. But who has the time to spend hours playing a game?? Graphics are cute, though.
