Happy that HaremHeroes is one of the few :-D.
Our game is far from being perfect, but can't be blamed for not giving enough "explicit fan service" ;).
I'd wonder what japanese would think about our game... probably that it's too hardcore :)?
Anyway, I've played all games available on Nutaku and I agree with most of what you're saying. But you need to understand that games being developed primary for a japanese audience, it's understandable that not everything matches expectations from a western audience.
