This game has been unplayable. I understand the need for ads and that's not even the issue. Every time I go to finish a level in the event, it crashes and I have to restart. In particular, it happens most often when you make mistakes and can watch an ad to erase them. But it also happens near the end of levels and you have to restart as the screen stays black. I've enjoyed this game, but the amount of crashes makes it not worth it right now.
