Terrible – Diggy's Critical Train Subway Driving Review

Unfortunately, 1 star is the lowest I could rate it. Can't play more than one level without shutting the app down, due to the fact that ads just keep popping up. You sit through the first one, or skip it, and before you can start the next level, another one pops up. And then another one, and then another one.
