Any news? It's been a long time since there was any news of this wonderful VN...
I’m sorry if this becomes a rude answer. Meanwhile, the game is actually really good we know that it is a hobby project. Meaning that he will work in this VN when he feels like it.
I understand the feeling to want an update already after comparing dates since the last update. But he might have been having problems or something in IRL, I do not know anything besides that it is a hobby project. So be patient, soon we will get something at least. And if the project no longer gets updates, we can create our own stories just from this, as a base.
