Our Darker Purpose is a story about a stylised school/orphanage from which all of the teachers have vanished, leaving the students to form factions and fight to the death, which is precisely what children do, as proven by the terrifying reality television show Lord of the Flies. To make matters worse, all of the furniture is haunted and most of it has teeth. And the school is sitting on top of an otherworldly abyss. With random item drops, character customisation and a Zelda-meets-roguelike vibe, the whole thing looks like Isaac has been dragged from the basement and dropped off at the boarding house on the borderlands. The little blighter even makes a cameo appearance. To nobody's surprise, there's a Kickstarter and a quarter of the $40,000 has almost been raised.
While the game will almost certainly have some tricks of its own up those starched sleeves, it does look a lot like The Binding of Isaac. Presumably with more pinafores and less poo.
