IOS game issue.

Does anyone happen to know what happened to the IOS game “Zombieland”?

The game was there at one time, I had it downloaded and was playing it without any difficulties but then after not playing it for a few days I went to get on the app and it kept saying it wasn’t connected to the internet. Eventually I searched for answer on Bing and apparently the game should still be available and playable but when I search for it through the App Store nothing at all comes up.

When I go to the main website for the game or look for it through google play it will appear available for download but when clicked on a box appears saying this game isn’t available in your country or region.

Anyone have any solutions?
