Of course the story has improved. This game at least *has* a story. You sound like you want a clicker game, though.
I like all the game, and I like almost every detail in it. With the exception perhaps of Diane's story, that one is almost rediculous. But still far from bad or pointless. The monster girls add to the atmosphere, and nobody forces you to play their quests.
The wrestling scene may well be the beginning of coach Bridges' upcoming story. Kim might be part of the main story. And if not, who cares? Did not clicking on Kim hinder you boinking any girl at all?
Nobody can do it right for everybody, so much is clear. I do not want to play a game where I, without any hint of a story, can go to every girl and click the "fuck" button. Too much grinding is also hardly fun, but I do not think this game has that problem.
