Hi, thank you for reaching out! While I’d love to add German to the game so your son can play with you, the team and I haven’t touched the game for years now. While I could go back in there, update it and add a new translation, I don’t know how feasible it is. Some essential files which weren’t on our work repository have been lost due to disk failures, which shouldn’t prevent new builds (they do prevent ports to other platforms), but I can’t be sure. I can’t promise anything, but you can send me an email if you still want to translate it!
