I don't know where people are drawing the conclusion that Triss is suddenly a bitch.
Something you have to understand as a developer, there is only so much you can fit into an update and keep the plot going.
This update, AV could fit in 3 sex scenes, and had to end the update story wise where he did while paying off the 3 relationships he could.
He decided to include a (very light) femdom scene for Triss.
If you actually play the scene you would know what I'm talking about.
Each time she does something, you get her internal monolog showing how unsure she is of herself doing this and how she NEEDS to be in control right now to keep herself from giving into the MC.
She mentions that from the research she did on the internet, it shows men like this, and if you look at femdom stuff... yeah, it be like that. lol
She doesn't "Throw a fit" if you disagree, she instead suggests that they just cuddle with her and the story moves on.
Would it be great for an alternative scene (where Triss is submissive instead) to be here if you were not interested in femdom? Absolutely, but considering AV had to keep the story moving to resolve the plot in 2 more updates, I don't begrudge him not putting in that extra work.
Same thing for the les scene with Mom&Aunt, he's working toward a harem ending and only has given himself 2 development cycles to wrap up a very large story I'm sure he was hoping could go on for a long while and I don't know about you, but I'd much rather have a satisfying wrap up of the story then alternate H-content.
Also, the developer isnt just abandoning this game.
He sees there isnt much support so decided to end things here and move on to trying something new because financially speaking, the game is a not successful despite this being one of the best HS VN's I've ever played. That combined with him being a 1 man developer, balancing college, he's obviously self conscious about making sure the translation is good but has no one to do so now, and the hordes of backlash he gets each update... I do not blame him at all. That's stressful when you are already balancing so much else in our life and just trying to put out a quality piece of smut for people to enjoy.
Again, I really hope AV decides to continue this story and instead just shelves it to come back to later because I truly do love this VN.
