It's a good game but all the pop ups. It gives you a free mega boost but wastes 30 seconds with pop ups. I got to do 2 levels & I would've been able to do a third but it made me go through this whole story thing for the tasks and rewards thing explaining how it works even though I did the first one. They need to pause it when you're not in levels or at least when going through those pop ups. When you buy it or get it free the game makes you waste 2 minutes of it. It's just infinitely frustrating
