This game was a total waste of time. All you do is watch ads. Oh, and spend 5 seconds mowing some grass that I've decided has no purpose except to lead you to another ad. Any ways, my son spent a lot of time watching ads only for the app to the require him to watch 50 more ads...then another 20 ads. The extra 20 ads was supposed to speed up delivery time by 1 hour per ad. Okay, fine. But, the timer that remains (4 hours) stops every time you exit the app.
