I think you complain too much to the developers for the little content they are offering.
I would like you to see the other point of view too, a developer has to create the maps (from stage 1 to 8 + the halloween and christmas maps) also the modeling of the girls, the monsters that are there, the animations, bug fixes, game story, testing, different clothes, minigames, store, skill kit, side stories...
If you really knew how much time and money it takes to do that you would stop asking so much, the developers have to take benefit of what they have created and the time they have invested (and thanks to that one of them has been able to improve his computer and make it more powerful to test the game better) besides that to the "free" users they gave us the harem room, which was planned only for the platinum plan (I think I remember).
If someone here really thinks that it is so easy to add things by the way, then make a game and you will start to understand what I mean (I have not created one, but I know the basics).
I also forgot to say that people deserve breaks, life is not just about focusing on developing a game to the max.
