I have been paying this game for several months and truly enjoyed it. However, I am now un-installing. I've reached a very high level and now find that the game freezes up and does not allow me to advance. What a disappointment !! I don't know exactly how some companies set up these games, perhaps they are not designed to advance. I found this game great, but am highly motivated to write this bc in my opinion, it's just no longer worth the space it takes up on my tablet. Shame on you !!!!!
