I'm pretty sure Princess Trainer and Witch Trainer were finished way before 2018 and 2019, and I'm almost sure Witch Trainer started development after Princess Trainer (not gold) was finished. Don't know where you got those dates.
You are also forgetting Magic Shop, which in my opinion is one of his best projects and as important to his "career" as WT and PT. It's when I started following him and it still has a decent amount of content despite the gameplay, and most importantly, like PT and WT, the art has consistently good quality throughout the whole game, unlike his other games including SC34. Now that I think about it, the way he's developing SC34 in the last few episodes, I think that kind of content would be better suited for Magic Shop. It would probably be easier and less stressful for him (as he wouldn't have to worry about the plot and character interactions and other shit), and it wouldn't turn SC34 into the inconsistent mess it is today.
PS: Oh yeah, I also agree with you, he has no work ethic and as he gets older (and gets more health problems), he distances himself even more from his golden days. He has missed his best opportunity to grow back when he had the time, the money, and the drive to create new projects, and as much as he tries to convince us and himself otherwise, those days are never coming back.
