There it is! The first (and probably last) patch for ArkX is published on the MarketPlace.
If you already bought the game, just remove and re-download it. Many things have been improved, and the game became way funnier. Check the site to see the vidéo of the extension.
And here below the first review on ArkX!
(The review is based on ArkX 1.0 (Without the patch))
