Over 6 Weeks since the last Update.
You do realise that the Work In Progress posts are updates, right?
There's been at least two, if not three since 0.34 Final was released.
Last post on his Patreon page is 9 days ago... 9 days, not 6 weeks. It was about the pregnancy content.
This year when he was ill was the first time that development had to pause for something that wasn't his annual vacation, and that's why there was a massive delay to last release.
I think he went on a first vacation only this summer.
He takes a vacation each year, and has announced it each time.
The only change from that was this year, when he was pretty badly ill which caused a delay in 0.34's (I think. That or 0.33) development/release. Between that and working on the upcoming pregnancy system (Janice first), I'd say that he's both playing catch up and working to implement an unfamiliar system, because people want their preggo-porn.
Personally I'd rather it was kept as some sort of epilogue content once KST feels the game's "complete".
