Mouthwashing instantly became a cult horror hit when it launched in September 2024. Claustrophobic and evoking a palpable sense of dread, Mouthwashing released to widespread acclaim, its low-poly visuals and grotesque atmosphere both surreal and transgressive. Coupled with provocative commentary on corporate malaise and patriarchal violence, it has inspired deep conversation and analysis. When it isn’t making a statement or causing a scene, Mouthwashing offers moments of melancholy — opportunities to reflect, question, and revulse. 

Dig into the unsettling, desolate tale that makes up this modern horror classic in Mouthwashing: Design Works. Featuring in-depth interviews with the studio’s founders — designer and programmer Jeffrey Tomec, art and narrative design Johanna Kasurinen, audio designer Martin Halldin and producer Kai Moore — Mouthwashing: Design Works delves into every nook and cranny of the game’s development, its myriad influences, and the macabre secrets behind its ill-fated cast and the Tulpar, the grimy, dilapidated freighter the game is set in. 

Authored by Khee Hoon Chan (Polygon, The Verge, Edge, Unwinnable), winner of New York Videogames Critics Circle award, you’ll learn more about the game’s fragmented, non-linear narrative, parse the Tulpar’s hallucinatory space, and discover how the auditory nightmares that permeate its hallways were conceptualised. Mouthwashing: Design Works is a meticulously crafted homage to one of the greatest contemporary horror games.
