@Turdicus @skylar @yockeypuck You see there's a lockdown for a pandemic but they're sealed inside, not knowing whether or not it's even real so they end up slowly starving and going insane together until they finally give up and murder/eat their demon worshipping neighbor (apartments) when he tries to summon one
it's a visual novel type of thing so it's all boring dialogue, the characters are cute enough archetypes to both sides (broody sexy emo boy with cute hair and a big sweater+ protective older brother all the other girls want for the girls, a high-energy affectionate seductive smugly correctible brat gf-sister for the boys)
Since it's a novel thing there are pathways though, so the canon may not be actual incest, it's an open ended choice players can take? Maybe?
