So I played the game for about a week or two and got pretty decent upgrades for my towers. I didn't play the game for a cople of months and they apparently reset my points. Well I went to the menu to add my play store account to it. I played today and feel like I made some decent progress. Well, I exited the app and they asked me again if I wanted to rate them, I said no. All of my progress was deleted AGAIN after that. What's point of a game that doesn't keep up with your stuff? Avoid this game
