Not available

I've been waiting amd waiting for a long time but in Google Play it only says that "this item is not available in your country". I can't download any version of Cupcake mania. I've searched but Cupcake mania is not in google play store. I received a goal to download it, but it said its not available in my country (Vietnam)

This game is not currently available to all players at this time. We'll let our Development Team know your interest in this, sorry for the inconvenience!
