So I played this game to completion so far, and here is my honest review (these are all opinionated and contains some spoilers).
There is an excellent amount of content, the characters are overall pleasant and feel fairly realistic (in the sense that they aren't just walking sex dolls for the protagonist). The animation is outstanding and the model work, despite the occasional bug or awkward frame, look excellent.
Character review:
Azraesha is such a darling. Despite being the first girl introduced, she is never overshadowed by the rest of the girls. I love how she has her own story, goals, and aspirations. She feels like a person who does exist outside of our character and the writers strike an excellent balance between her teasing, matureness, lewdness, and cleverness. She never feels like a typical succubus bimbo and is her own character and I adore her.
Caitlin is adorable and it's a lot of fun to see her grow more confident and assertive, occasionally falling back into her old habits, but I'm glad she actually does display her proficiency and knowledge in magic and how she isn't always a helpless "pls help protagonist!" Although it takes coaxing sometimes, she is a growing character and I thoroughly enjoy her storyline!
Lyriel is a character right up my alley, and although her story beats confuse me a little, her character is pleasant to watch. It's nice to her see going from a hateful, arrogant bully to a kind and begrudgingly appreciative person. Also the sex is PRETTY damn hot.
Naomi I like a lot. She's full joy and life and chaos. And I adore her relationship with the less assertive Caitlin and the way they complement each other. Naomi's recklessness and Caitlin's timid restraint. Her story arc is difficult to sit through, in the sense that it's pretty hard to watch characters you love fall apart a little, but I'm glad it's resolving ok. In terms of overall character, would love to grab a whiskey with her. Besides that, I like how her flaws ground her more as a human being.
Yona I... wasn't too sold on. Don't get me wrong, a strong, powerful woman is a REALLY appealing character. However, the way she is distant and a little aloof, although I know it's part of her arc, makes it difficult to find that connection with her, and the way she has sex with us so easily kind of makes it feel like a bit of a dry character overall. Hopefully she gets more development over time.
Finally, Blair is unfortunately a bit of a nothing character to me. Most of the time is spent trying to convince her of magic, after which she kind of just does.... nothing. Her design is nice, although I liked her better in her heavy fur outfit than tits out, and her voice is fun to read, but up to this point, she simply hasn't offered enough to the story to capture my interest yet.
In conclusion. Excellent animation, background work is amazing, models are great, dialogue flows well, characters mostly amazing, story is good (I like how it doesn't focus solely on the sex and actually has plot progression) and the protagonist is amazing because he seems like an actually decent person that makes good decision. (I spent too long on this but thank you for working on the game)
