Now, this delay is expected in developing a game like this. FDW don't have a big budget and yet they are maintaining steady artworks that do not break continuity in style often, and they also have to add to plots and subplots (via storywriting and coding) without breaking the game in like the MC. On that note, I should point out that even if you get Rye's name early in the game, it still shows "horny jerk" in places.
So yeah, it will take them time and at least, they are trying to do it better than some *cough cough* koda'r *cough* with the small team of contributors they have.
Furthermore, it is not like they can hire people to work on it part-time often, let alone full-time. Aside the budget, not many developers (talking about people like me) can show this as Open Source contribution or Game Development activity in our Resume without social repercussions. At least not in the society I live in.
