After incredible wait we're back with a fully german version and DLC.
To switch the language version, access properties of the game and on the "languages" tab switch the language. Be warned that it's a long download, though.
Also you might notice that a DLC is being available. It contains game soundtrack, beautiful hintbook and as a bonus a game called J.U.L.I.A.: Untold. It's a puzzle game based upon the blueprint construction puzzle from J.U.L.I.A.: Among the Stars and offering 5 unique pieces of story before the game actually happened.
I hope you will like it and happy listening / gaming!
