I just want to add a few things real quick, especially now that I know you are learning German (how cool!).
You might be pleased to know that you actually managed to teach a native speaker some German.
When I played your game, my first instinct was to dismiss the Waldleute as some bad translation because I had never heard the word in that context before. After some googling I found out it is an actual thing with lots of lore attached to it. (I probably would use the term Waldgeister because Waldleute is a bit ambiguous; they could be just normal people living in the woods, but it is still correct.
Also, no need to apologize for anything. It is me who needs to apologize if I sounded dismissive about your use of German in this game. It's actually pretty cool that you are learning it.
All the German in the game was actually understandable. Just a bit foreign sounding but that is fine. I could imagine the characters are German immigrants that now live in an English speaking country and have acquired an accent. I think even the grammar was fine as far as I remember.
Oh, and if you ever need help with German, maybe for your next VN project, please feel free to reach out to me. I would be glad to help.
