Is there a permanent bad state? Or did the bad states disappear at the end of the battle?
Every
transformation is permanent, but there's a way to remove each one at your leisure. Some transformations give you immunity to others, but if you aren't immune, transformations can be applied even if you aren't in your normal form.
States, on the other hand, are temporary (timer on turns, and walking around if you end a battle with them). Some alter your appearance slightly, and might change the the character to only be able to use sexual skills, but for the most part they just serve as a way to temporary take the character out of battle.
Some specific states are permanent, like mind break, which just disables the character until you can get an item to revive them.
It's much more game than porn. If you are ok with transformation and futa, (there are no men in the game, just women and women with penises) and don't mind your porn games not having hardcore porn in abundance, you'll have a wonderful time.
For quality, it's something like divided reigns with the usual RPGM assets. They have a lot of systems that distance it from the usual RPGM slop, but not complete overhauls that make you question the engine it was build on like Ara Fell.
Edit: forgot to say that transformations aren't at all a bad thing. They each serve as classes in the game, giving you the ability to basically change your skills and play styles as you wish. If you've played FFXIV, it's kinda the same thing, only the enemies can change your class during battle.
