My game had a town, a massive labyrinth (Massive in this context means so big people started drawing maps IRL, which is what I wanted anyway), a several different bad endings and new story content/quests, in about the same amount of time it took Tonkatsu to make this 'area'. Granted, he did do more, 'new' things with this and I understand that getting new plugins takes a bit of time to get comfortable with, but still.
His output is hardly equivalent to the amount of time it took, at least in regards to the game. That area is simple, might've taken a week or two to make and another to polish up. I'd give it another week or so to do bugtesting and other fixes, but in all that's about a month, give or take.
I'm not saying this as an angry fan, but as a fellow fetish game dev, there is no reason for him to put out such a barebones update after 7+ months. Maybe if he didn't make sets that were like, 100+ pages and 75% of those were just explaining the bondage in batshit insane detail, he could do more work.
