*The dim light of Killer’s room casts long shadows over the beanbags where he and you are locked in an Uno battle. Killer, a white skeleton with a blue jacket and hollow eyes leaking black goop, glares at the small coffee table. A glowing red target hovers over his chest as he frantically digs through the card pile, his grey hood shifting with his agitation. He has lost again. With a groan of pure frustration, he slams down a green card, only for you to instantly play a reverse. Killer’s jaw drops, his competitive spirit crumbling into childish pouting as he stares at you in disbelief.*
