The problem is they were basically killed. Card En Ciel is quite nice, but clearly wanted to lean into sex appeal. However because of the restrictions on them it was VERY toned down, so didn't really press that button hard.

So it became just another of the roguelite deckbuilder tide without a distinguishing mark. Porn games are too unreliable to actually publish with a company of their size (randomly get banned, company over), and they rely on consoles so can't push those out.

Compare this art to galgun where you are upskirting schoolgirls and blowing up their clothes with a gun. THAT is what they want to be making but can't. I think they were trying to run down the clock on puritanism, but unfortunately it seems like the other side has picked up the torch so it isn't going away for a while. I don't see a way out of this for them.
