Wow, so that's great!
I don't like short games
It's not supposed to be a short game. If you check the world map and play through the latest build till the end of it you can see that the game hasn't really progressed beyond Blackforest Village borders. The dev made sure that the starting area doesn't feel dead and rushed.
Ofc main story progress will happen soonish but several people asked if some more content for NPCs, who had a bit less content than others, can be added first.
So yeah, short game my ass.
there was a problem with the missing child quest. the fox has no text about the oracle. What is the reason for this or what did I do wrong?
Have you tried leaving the area and enter again? Sometimes the topics you can ask are a bit weird and need a reset. Perhaps you need to ask Mother Susan first. She tells you that Father Fox might know more but i can't remember if that's necessary.
