I only played the Dual Love Route so far!!! Slight "Spoilers" ahead!!!
This is the first game (if you don't count LoML) without animations, sound and music that I tried for the fuck of it because i don't have anything else to play. I don't regret it one bit.
Okay, hear me out, I get why people get uptight about this games rating and give it three or four stars, but man they are either stupid or just searching for a quick fap (which this game is not, and I don't judge since I too do that sometimes when I'm too horny that day XD )
Story 5/5: Yeah, you heard me, five stars for the story so far, I have played every possible incest game 5 through 3 stars on this site and man, even if its just slice of life story it keeps you hooked, I have been feeling so burned out from these, I've been searching post after post for some good incest done right where the family you try to seduce/romance/corrupt feel believable, the reluctance, fear of being found out and the heat of the moment actions are done so right i might have fallen for the sister. This game tickles my fancy in so many ways, even when it does not have Sounds, music or animations as i said above, I can't tell you much without spoiling it, but the sister is written so well I rarely feel like that for a character in a game.
This one is definitely up there with LoML and the other big boys.
Dialogue 5/5: The Dialogue feels very real to a point where it feels too real in some says, you can feel the tension, emotions and because of all the buildup, some characters (again, i cant say too much without spoiling), even when you just met them you feel for them in some way.
The Sister is by far the best written one here, the MC has very good writing too, yeah sometimes there is too much text about what he is feeling, you have to realize he is just a confused, scared virgin nerd that does not know how to deal with all that is building up inside him, at the same time he has no one to talk or help him with this, so he just keeps it inside him, but its written so well he and the other character actually feel like they are just some 18-year-olds full of hormones and in love, this is the first time I didn't skip though them and actually read them, every single line.
Renders 5/5: Quite nice renders, don't get spooked by the previews, you get immersed so well into the game if you have some good background music of your own that you kinda forget one of the girls is white as a ghost XD the Environment is very nicely done, feels like actual home.
Models 5/5: they are believable, no balloon tits or huge asses that defy logic here, feisty runner sis with a petite body to die for, sweet yet hot best friend that will fill a nice dress just right. Yeah, i think you get the point XD
Animation /5: no rating because i believe in the dev and im sure this game will be on the front page of the weighted rating in the future.
Sound /5: same as Animation
Music /5: same as Animation
TLDR: No Animation, no Sound, no Music 10/10 would recommend! Topic about Rape comes up quite a bit, don't get spooked by it either and just download!
Edit: Forgot about the Models, added section!
