Hey! Not finding this on Google Play at the moment.
Unfortunately the game was removed from Google Play, because after we removed all the ads and in game purchases, the Google automated tools still thought the game contained ads or was tracking user information and we were not able to contact a human at Google.
The file you can download here is the last version that was on Google Play. It's free, doesn't contains ads or in game purchase and shouldn't require any authorization (doesn't access internet... ).
