Despite being the newest high effort, good hentai rpg, I still think they fumbled one the key things games like Karryn's Prison realized.
Regarding H mechanics in rpg games, most games, including this one, takes the "H mechanics is a way to make the game easier" approach, you basically get infinite money for free if you level Beauty instead of Speech, the Chastity debuff to Prayer is not even that bad, and can be easily sidestepped by switching to magic if you want, as they share the INT attribute. There's no Order mechanic and you also level by doing sex scenes, so you're just wasting your time going for a pure Combat/Speech run.
Karryn made H mechanics it's own playstyle and tightly woven with the combat, I think this philosophy could be reconciled in this game with not many changes, but oh well. It's different, not inherently inferior by any means, but I sure do prefer how Karryn does.
