Sucks. There are a ton of limitations because of a paywall, minimal to do if you don't have pro and this isn't fun enough to pay for pro. 2 days in, go for my 3rd streak and levels 3 and 4 are suddenly restricted and only playable with pro. They took away a function from the free mode, leaving even less to do. If you want money that freaking bad then just charge for the app instead of screwing over the free players and taking more things away and leaving us with even less. Joke app
