Have you ever wondered why does he not show the interrogator's face if has already put in the effert to create/model it? He has not done so because the interrogator is the only one that has dialogues. If he shows her face, he will have to lipsync her dialogues which is a task unto itself.
So first you say he milks his Patreon (SubscribeStar actually, but that's beside the point), but then you critique him for doing something that saves him work and time? Doing lip syncing would only add another reason for him to further delay the releases, wouldn't it?
And let me play devil's advocate a little here. Do we have the full picture of what goes into making these animations for Animopron? Does he work on it full time, or is this just a thing he does in his spare time when he feels like it? Does he have any obligation to deliver a new part within a certain time span?
Milking supporters is something that comes up a lot in this forum. And I mean
a lot. But if you were in the position of earning as much money with something you don't have to put much work in, if that's true, wouldn't you also do that?
