Likewise, I'd like to see the Tris/Charlotte/MC dynamic fleshed out more but, at least the way that I'm interpreting it, is that the dev mat be getting a little tired of working on this story. I'm getting burnout vibes. Remember, this game is, what 3 years old? That's quite some time to be working on one story of Any kind, let alone a VN with people constantly clamoring for updates, some of whom are down right disrepectful or abusive when they can't get it as soon as they feel it should be out. Evenmoreso, if what you're doing is not your main source of income. The dev may think that enough's enough and wants to move on to something fresh. Or just be done with it to take a breather, look back and admire his/her handiwork. I can Certainly relate. At any rate, let's continue to support the dev. The end appears a ways off yet and who knows? The dev maay change their mind and stick it out for an extra season or two. There's a lot of time for contemplation.
I know he took a break, but it's always a bit worrying when a dev a month after the last update shows a development graph this "empty", hopefully now he can find the inspiration to keep going, this game is great, well above the average incest fantasy fuckfest.
Back when season 2(knowing that the plan was 4 seasons) was concluded i felt very strongly that sex with either Triss or Charlote should've been part of the season finale, and then the other one halfway through 3... maybe ending 3 with them finding out about each other.
Now(if we stick to 4 seasons) it seems we have a lot to go through in a condensed schedule, Triss and Charlotte finding out about each other and dealing with it, dealing with the dad, dealing with Katrina, seeing how the other girls feel about this...
And of course Bea/Denise are still waiting to join the fun... That's a lot of stuff.
It would probably be best to have 2, five episodes seasons, or a very long S4... but that may conflict with his desire to move on from this story and these characters.
I hope he finds the motivation to do the best for this story, this game deserves it.
