All three stars are for the artwork. Seriously, the renders are amazing, some of the best I've seen (if I were to quibble, I'd want them to be less dark for the night scenes). The animations are excellent too - they are really well-integrated into the flow. There is a lot of talent and skill in the artwork.
But the other trivial details (plot, characters, writing) are... ahem.... somewhat lacking in quality.
And I'm not sure it can be fixed.
The plot is... listen up and tell me if you've heard this one before: MC living with his mot-er - landlady and roommates. Landlady is horny angel (she gets my vote for most beautiful CG babe on this site), Roomie A is nerd, Roomie B is badgirl. There's a femme fatale who may be evil, and a sleek, ice-queen. And a gorgeous nurse still to, er, come. Oh, did I mention demons? There are demons. And everything is kinda dark and neon-lit. Yeah, it's another one of those.
I personally find the occult kinda boring - especially when you've also got drug dealers and stuff like that - real life menace is always better. Updates are slow and spare for this game - totally understandable given the render quality. So I would keep the focus just on one mcguffin (not the demons), and ramp up the threat.
Writing is pretty clunky. A lot of it reminds me of bad kung fu movie dubs from the 70s. People say things like "I see you want to f--k me hard," and you just know that's not what they actually said in their native language. I know it can be hard for non-native English speaking devs, so here are my suggestions for improving dialogue:
1. Have people say less when they talk.
2. Always ask yourself, is this really necessary if you're going to write what a person is thinking? Nine times out of ten, it isn't. If you need to have someone think "I wonder who's at the door?" don't write it. Just use a montage of two images: closeup of door, closeup of person's frownie face.
3. Don't have people describe what they're doing while they're doing it "Holy f--k, I'm in so deep..."
4. And never, ever, ever use narration.
The MC is all over the place. Is he 12? He acts like he is when he's at school (university? seriously?) Is he a confident sexmeister? Well, according to the car dealer's wife he is. Or is he a pathetic, lurking pre-vert who creeps around bedrooms at night? Yes, that too. Night creeping is so stupid. But if you want to spice it up, reverse the roles. Have the girls check on him. Why do devs never realize that if you want to promote your MC as a stud, night creeping is exactly what he wouldn't do?
Let's just decide who the MC is, and keep him like that.
(Sigh). We're at V0.6, so it may be too late. I just feel kinda... sad, y'know, when you have such outstanding rendering ability weighed down by such mediocre, derivative writing. The girls are gorgeous, the sex scenes are erotic AF and if you wanna fap you will fap. Use your non-dominant hand, and pretend that it's a really badly dubbed foreign movie if that helps.
