For me it is not so much the delay in development, those that have been here awhile are used to delays. There are developers that I like a lot and respect and even support on Patreon that haven't had an update in 6 months. It is the fact that BlueCat refuses to communicate with his Patrons, seems to have no plan B if the actual developer stays sick or just decides to do something else with his life, and appears not to be in charge of his own game. If he just sent out a weekly update with some sort of information, something like "Hey guys, the key programmer is still under the weather this week, but we got a few code updates, and I am working on the renders for the next update. Let's hope next week has better news.", it would show that he actually values all the people that have been giving him money all these years.
Since BlueCat doesn't do this, it just shows that he doesn't care about his fans or his patrons. Skummy, who I appreciate, can say whatever he wants, but BlueCat is the developer, and BlueCat is the one receiving money to develop his game. It is his responsibility to let his fans know why development is stalled, why he hasn't paused his Patreon, and when the fans can expect some progress. Not a good look for a developer that relies on donations for his game to proceed. Communicating with the fans is a key part of the donation model. Maybe he is bitter about something, but this doesn't bode well for the future of the game, in my opinion. Is he just waiting around until the monthly donations on Patreon drops below a certain amount, say $2000 a month, and then he will finally do something? Like find someone else to work on the game? Nobody knows, and BlueCat isn't telling.
