A.V. Club writes: "Sleep Is Death isn't so much a game as a new storytelling medium. There are no points to be scored or power-ups to speak of: It's just you and another player, improvising your way through the narrative, trading off turns that last a mere 30 seconds for as long as both parties are willing. As your annoying friend who does improv will tell you, the guideline of "yes, and" permeates every facet of real life whether you realize it or not. Especially here, even though half the fun of playing against total strangers online seems to be subverting the storyteller's vision."
