Where you can play today
On 2026-10-28 the US Steam API listed Mouthwashing at USD 12.99, discounted 40% to USD 7.79. Platforms on that response were Windows only: mac and linux were false. Steam Deck is Verified in the deck compatibility data used for this site.
No official iOS, Android or browser version was identified in the current publisher and store listings. Historical reports of an itch.io page becoming unsearchable are not proof that a page never existed. Use the official stores listed on the download page.
What the crew pages cover
Five people crew the Tulpar: Captain Curly, co-pilot Jimmy, nurse Anya, mechanic Swansea and intern Daisuke. Polle is the company mascot. No numerical ages or heights were verified. Writer Johanna Kasurinen gives Curly’s full name as Orion Carling in a public post; the character page identifies that primary source.
The plot pages separate the premise from marked story revelations. The walkthrough pages link the written guides supporting their codes and strategies. The valve puzzle and other details with only one accessible source are explicitly labeled; no unverified rotation count is presented.
