Live-action web/indie series, gothy/emo teen girl, armed, sitting on roof as black slime tendrils surround the house

Probably from around 2010 or later. American or Canadian, probably. Protagonist is a misfit girl with a dead-bunny style hoody I think. Her mother disappeared years before, there’s an underground fungal mega-organism under the graveyard behind her house. Mom’s down there, dad gets taken, and then her lil bruv. There’s a shot of her sitting on the room, looking bored as black slimy tendrils grow up around the house and she gets ready to fight. Thanks in advance!

Are you sure it’s a series?
