ok guy... there is no need to go off on them like that especially in such a condescending way. They don't owe you anything. If you don't want to support something or feel unsatisfied then just don't support and move on.
I found this game over a year ago and with a bit of research figured out they had some things going on. There are countless VNs that go silent for a long time. Of course that sucks but the people who work on these projects have lives and things happen. We don't know what they navigate in their day to day life. This kind of aggression is ridiculous and results in an unnecessary hostile environment. Many creators are not professional game developers and are trying their best to share the stories that they want to tell. Your attitude will accomplish nothing.
