First off, I bought and played this game before its Steam release, and it was well worth the purchase for me. It might not be for you, depending. I see this game as being for generally two kinds of people. 1.

I like this game. It's fun. There are a lot of good things about it, the story is nice, the characters are cool, the concept of transformations is extremely well done. The fetishes it involves... ... ... Not going to lie here, nice... Large spoiler warning read on if you don't mind having some battle stuff and game mechanics exposed. But it has it's flaw…
Goodness, this game has a number of things that seem rather.... inspired, and the contents are lewder than expected but the depth of content and mechanical thought go beyond anything I would have expected for this price.

About This Game
NOTE: ALL depicted characters are of 18 years of age or older.A Huge Open-World Hentai RPG Awaits!
Explore the world of Gianna as Princess Lilina, who's been tasked with gathering the six legendary Orbs as part of a plot to overthrow the royal family.
Along the way, she'll make friends, fight enemies and bosses, and experience many, many different status conditions, ranging from mind control to transformations to just about anything you can think of!
Experience this new highly-replayable and content-rich RPG where game mechanics and erotic content are intertwined in completely new and unique ways!
Over 50 Versatile Status Conditions!
Gianna is a world of many perils, with over 100 enemy types who can inflict your party members with a wide variety of status conditions. These conditions will change your characters' portraits, their statistics, and sometimes even their class!
In addition, almost none of these conditions are strictly negative! A character may be turned to stone, but a passage may need you to place their statue to proceed. There may be a small hole that only a party of miniaturized characters can pass through. A character may be transformed into an onahole, but you can use it on enemies to help defeat them!
You can keep track of all of these status conditions in the Status Journal, which updates whenever you experience a new one!
A Wide World of Possibilities!
Take the three starting party members and seven more that can be recruited - each with a unique base class such as Mage, Warrior, or Rogue - and add the variety that comes with class-changing status effects, and the possible combinations for your party are practically infinite! With your chosen party, face off against memorable bosses and fight your way through over a dozen dungeons with unique mechanics!
Level up and spend Job Points to unlock skills in the order you choose - some of which will still be kept even after changing classes!
Bad End Cutscenes!
Losing or surrendering to an enemy will trigger a Bad End cutscene, featuring a wide variety of fetishes, including mind control, petrification, enslavement, encasement, possession, gyaru/bimbofication, time stopping, corruption, and many more!
Getting a Game Over this way only sets you back slightly, as you're not forced to reload a save file. And after that, you can re-watch that Bad End cutscene as much as you like! In addition, defeating a boss unlocks Bad Ends you haven't seen in that area!

Horniness scale
Each game gets a score from 1 to 5 hearts. Higher means more explicit adult content.
| Score | What it means |
|---|---|
| 1 | Raunchy / softcore — suggestive themes, light fanservice, or mature humor; little or no on-screen explicit sexual content. |
| 2 | Spicy but restrained — clear adult intent (nudity, strong innuendo, or brief suggestive scenes) without sustained explicit focus. |
| 3 | Clearly adult — recurring sexual content or nudity as a meaningful part of the experience, but not the sole focus of the game. |
| 4 | Strongly explicit — graphic sexual themes, extended explicit stills or text, or gameplay built heavily around adult situations. |
| 5 | Explicit and often animated — graphic sexual content that is frequently animated or interactive; core to what you see and do in the game. |
