So how are they going to "make the story darker" but at the same time "Make the MC stronger and more in charge" while adding more relationships and romance stuff with the heroines?
Aren't these two things like polar opposites? You either have a miseryporn game like Limbus where tragedies happen every chapter or you have a game like Wuwa/Snowbreak where your MC is Chad ThunderCock where every girl is for him and he can resolve every problem without fail.
