Just finished 0.12. I am pretty impressed and want to share some thoughts.
I enjoyed the artstyle a lot. The environments don't look that good, but the important thing are the characters and they do. I dislike many 3d games like this because they tend to go for a semi-realistic look and it just tends to land squarely in the uncanny valley, especially when the characters start moving. The anime-artstyle here circumvents that problem nicely.
I also really like the characters. They don't feel as 1-dimensional as characters in theses types of games tend to feel. I tend to dislike the drunk-girl archetype in these games, but even she grew on me when she got more development with her witch career. The scenes are also really good. Normally most non-lewd scenes feel like little more than filler, but the characters have a nice dynamic here, the scenes are well written and even have good comedic timing. I had to actually laugh out loud at a couple of scenes and that is pretty rare. I also like the exagerated effects in some scenes, like the red eyes when you play hide and seek with luna.
The biggest problem in my opinion is obviously the performance. It's not a huge problem once you get used to it, but it's still annoying. I read that this is the devs first game dev project and I wanted to offer some advice, since the game looked like it was made in unity, but given that it's actually renpy I don't think I would be much help. I have to say it definetly deserves some huge props to make a game that's vastly more complicated than a Visual Novel using a Visual Novel Engine using Python as the coding-language, exspecially if it's your first project. The result is very impressive considering all that, despite the performance.
The only other thing that bothered me a bit was that it reads fairly weird to have people calling each other partner in a seemingly non-romantic way and saying it like it's supposed to mean something. I get it's supposed to be a stand-in for sibling/sister/brother to turn it into something non-blood-related? I feel like something like "best friend" would work better here. And some scenes need a bit of a rewrite to work with the stand-in, no matter what it is. Like the scene were luna and lucy reunite and she tells everyone that they are "Partners" only to then go on to say that people used to be only able to tell because her hair is the same color as the hair in luna's cat-ears. That makes no sense if you don't know what "partner" is supposed to be the stand-in for. A more fitting text could be to just say that they were both quarter-beasts and bonded over that to become best friends. It conveys the same information: That lucy is also a catgirl and that she and luna have a strong relationship with each other.
Anyway apart from those few scenes with a bit of awkward obfuscation in the writing, the writing is really good. Looking forward to more.
Edit: Also, I feel so damn bad for poor lucy, man. She's the first to support you, with you all the way and supportive throughout. But due to story she's the last to get anywhere with MC. She gets targeted and beat up in the street in a racially motivated hatecrime. Then Ari comes and Lucy gets all the hate for being "in a relationship" with MC, despite the fact that she was dead last on that account. And then in the end she gets stood up by everyone and mc f**king twice. And she still gets stalked by the racist girl. Poor girl just can't catch a break and we haven't even gotten to her hinted tragic backstory yet.
Also if you think about it, MC doensn't come across great with the red haired racists. He meets and knows the location of the girl who beat up his friend in the streets and because she doesn't attack him personally, since he is the "right" race in her view, he just lets it go? Not even telling Rebecca and Jimmy about it? It makes the last Delilah-scene a bit awkward too. Yes, Delilah, we accept you here just the way you are. There's a group of human suppremacist bandits right in that cave over there, but ignore that. They just beat up a girl right around the corner of your flowershop, so nbd, right?
