Mouthwashing on PC and Steam Deck
The Steam page lists Mouthwashing as a Windows game. Minimum spec is Windows 7 64-bit, an i5-6300HQ, 8 GB of RAM, a GTX 560, DirectX 11, and 3 GB of disk. Steam Deck is Verified.
What I saw
I read the requirement block from the US store payload rather than a copied spec sheet. The recommended block raises RAM to 16 GB and the GPU to a GTX 1050, still on Windows 7 64-bit, still 3 GB of disk. Mac and Linux flags were both false.
Requirements
Minimum: Windows 7 64-bit, i5-6300HQ, 8 GB RAM, GTX 560, DirectX 11, 3 GB storage. Recommended: i5-1135G7, 16 GB RAM, GTX 1050, DirectX 11, 3 GB storage. The store did not publish a frame-rate target, so this page does not invent one.
Categories on the store include single-player, achievements, full controller support, trading cards, and family sharing. Steam Cloud was not in that category list. That absence is not proof the game lacks cloud saves inside the client.
The 3 GB figure is required available storage, not a measured download or installed size. The game’s legacy requirements list Windows 7, but Steam’s store footnote says the current client requires Windows 10 or later. This guide has not tested a Windows 7 installation.
Deck, Mac, and Linux
Deck compatibility in the data used here is Verified (resolved category 3). A Verified badge is Steam’s label, not a promise about a particular frame rate.
There is no native Mac or Linux build on the store. Proton or CrossOver are player workarounds, not builds shipped by Wrong Organ. This page does not link to patched Mac binaries.
Version and file size
No current public build number, patch version, console file size, measured install size or frame-rate target was independently established. The PC requirements and Deck badge are single-source Valve metadata, not benchmark results.
