It's an enjoyable game. Play for awhile and then let your energy build back up. That way you don't spend more time than you want any given session. But if they don't get that boost thing out of my way while I'm playing I'm uninstalling.it cost you time and score on each scene. This is something new. If you touch the bar that is in your way it takes you to Google play. If it wasn't for that I'd given 4 stars.
