Fun game, but be aware that you need money to get anywhere. Starts off ok - you're able to get through the first two levels without boosters, but you absolutely need them to advance beyond that. It happens in shady ways, too - one coin shy of the goal, two likes shy, etc. It doesn't give you enough opportunities for free diamonds to make it worth it on top of the number of ads you have to watch. Don't waste your time or money.
