5/5 VN, easily.
Iwannabeyourdog2's writing is always snappy, efficient and to the point, and Sleepover Sim and Older Brother Sim have shown it can stay that way when depicting complex and tangled emotions, but Bloodlines shows that off in full force.
The fucked up scenes are well fucked up. The cute scenes are really really cute. The cathartic scenes are great catharsis. And the horny scenes are either fucked up, cute or cathartic.
I think Andre was made in a lab for me specifically. I know the story is finished but I would eat up anything with Andre in it. Just putting it out there.
Of course other characters also shine in this VN. I feel like they tap right into what makes an archetype compelling and build a genuinely tangible (sometimes loveable, sometimes not) person around it.
I almost forgot the voice acting, which amplifies the feelings of each scene by a lot. Great work to everyone involved.
If you're reading this, try Bloodlines, it's absolutely worth your time.
