Not in honey select.
Jestur is the only one that takes as long as Eternum 0.9, but he has always worked slowly.
The biggest time sink is animations, and Caribdis stopped doing them himself.
The level of quality in Eternum today means that updates every six months isn't feasible, even with an animator. But I doubt Caribdis himself is happy with the update taking more than a year. He has projects he wants to make in the future, so he's not trying to milk the audience on this one story.
Given historical trends, 7-8 months for his usual ~1500 render updates seems to be a reasonable expectation. With this one being more than 2200, 10 months is probably what he'd have preferred (remember writing time is going to be equal for both so it's not as simple as dividing renders by time taken for an average time increase). For a game like Eternum, with extremely limited branching and alternative scenes, and with the resources Caribdis has because of the game's success, a year is much too long.
I'm an Eternum glazer, but even I can't do the mental gymnastics to convince myself otherwise.
