It's not about them being secondary characters. My point was, that he wrapped up Jet's story in a lazy manner + only added 4 repeatable scenes, with Allison it was alright, yet he could've added 2 more scenes, so her content would be much more satisfying. It's just the thing about secondary characters: most of them have 7-8~ repeatable scenes (Nadine,Pam, phil's mom and etc.). As I said already, the update itself was not the problem, the amount of content it contained was a bit disappointing. I'm indifferent about futa stuff. I'm actually glad he added more variety to the game, since 30%~ of his patrons are into futa thing. I actually think it was a smart move to add futa content in the game, he also didn't make it mandatory, so those who are not interested in it can just ignore it. I hope he would add at least 8-9 scenes with Maria. Also I think he would turn the plot into different direction, I doubt Maria's quest would lead to Lucy's downfall, cuz if it does we would have to choose between Lucy and Maria. I don't think many people would like that. So I suppose he wouldn't continue plot in that direction, imo. I think he will add more content with Aunt Maggie later during Lucy's storyline, since MC would have to learn more about Lucy from Aunt Maggie.
I also hope next update won't be released at the very end of january ( like he did in november), but rather at the second half of it.
