Those are great recommendations, and I appreciate that some of them aren’t the usual picks. But in my opinion the biggest difference between those games and Tjord's are that: Tjord games are actually complete.
To be fair, most of these even without being finished (and even then, some are) typically feature more raw content than Tjord's titles. That's probably my only actual gripe with the latters actually; while the quality is top notch, being visual novels and featuring only a small amount of characters at a time means very few actual content. The story is extensive enough to pad the titles nicely, but sadly good stories are far more common over here than good corruption+body modification content.
I'd still take any new Tjord game over most, if not any of the recommendations I've listed, but another factor behind this are how much I like the resulting transformations' looks, which is why I'm cautiously curious about whatever they'll release next, since I vaguely remember Tjord mentioning that Valkyrie would be the last title using honey select.
Either way, I'll also mention
the village of nightmare series. I didn't do so in my other comment because it's more dated (especially visually) and might weird out some people by being a little bit more sadistic/nasty,
buuuuut it's still a classic and each of the multiple titles are
completed, and they tend to feature a loooooot of different characters with different corrupted forms.
