Low rating is for developer abandonment of app – Bingo Rush by Buffalo Studios Review

Is there anyone still playing Bingo Rush? I'm wondering if any of the other areas have the same issues as Sao Paolo? It does take a long time to unlock new cities, and to level up, but this is my fav game. I will play until I reach the end, in spite of the lousy lack of response from the developers, just want to know if there are any more cities I should avoid. Any info would be appreciated!
