Everyone is gangsta until the fire starts and then the AVN turns into a heavy gloomy cloud. The message of this game is the importance of conformism, if someone is bullying you, oblivious you can't comfort yourself and you have to fight against it, but what about death? You can't redo it, you can't fight against it when the death is sealed, the only way is to conform yourself and keep walking, and is hard as fuck. I don't consider this adult visual novel porn, it's nothing but a sad adult lesson, but a good one.
You might be right.
The problem is that someone looking for a sad adult lesson, usually doesn't seek it in a porn VN...
I would add that trying to deliver a sad adult lesson disguising it as a porn VN (just because porn sells better than sad stories) is misleading and unfair to his public.
It's like trying to trick your toddler into eatign vegetables by doing this...

...he's gonna be very disappointed!
