I used to like this game. It was a brilliant time waster, especially the challenge levels. However, having got to level 669, I stopped playing for a while. There's been a recent update, icon has changed, and I can no longer get into the game when I try. Have had to uninstall. Tried to reinstall and ... You guessed it, I'm back at level 1!! 668 levels gone! Uninstalled. Not playing again. Not happy.
