Demonpact: Clarice

An RPG adventure with 20+ characters to recruit, multiple endings, and no leveling system. Two hopeless nerds manage to summon a demon girl, but now they have to find another person to die as her demonic sacrifice instead of themselves. As the story unravels, they end up breaking the law as well, so the cops, bounty hunters, vigilantes, and pretty much everyone want them jailed and/or dead.
