Let's not go from one excess to another, the lighting is still good, compare it to older games like the Acting Lessons,Dreams of desire, depraved awakening,Man of the house,My cute roommate, Big Brtoher,Long live the princess,etc.
Good games, but still have their flaws with the way things look.
in Milfy the lighting tends to make elements mix well together, skin reflects light the way it should and it has a general sense of all around warmth where you can appreciate its many colors.
I don't want to put too many words into this, just to say that at least regarding the lightning it does not seem a fair assessment, because it still looks good, I can agree about many of the faults of the game, especially compared to ones of now, but when it came out it was ahead in many ways and is still looks pretty good.
