This game is a very addictive game. I originally downloaded too get coins for another game, but fell in love with it immediately. Been playing it for roughly 2 months now, and until recently I've had no issues. I'm on like the 4th set of 40 levels, and now after every board I pass/complete, I have to close completely out of the game, and restart to advance to the next level. If we can get this issue fixed, then I'd have no issues with giving 5 stars.
