Hello there,
so I have contacted Yury Appollov, the Developer of the Current iOS version.
I had a look at the app, found it passable.
When I reached out for support, he responded instantly.
What I am unsure is, if his attribution to the developers of the actual content of the game is sufficient.
Please have a look at the App in question here;
Cataclysm Dark Days Ahead & BN on the App Store (apple.com)
And share your feedback in this thread or (preferably, he responds quite fast) via his contact;
Catalysm Roguelike RPG support - Jira Service Management (atlassian.net)
Thank you for your time and warm regards
