Games like Mouthwashing
If you want another short, bleak, first-person story after Mouthwashing, the closest official neighbor is How Fish Is Made, also by Wrong Organ and free on Steam. Iron Lung, SOMA, and Signalis are the other names that survive a “same mood” test.
What I saw
These are editorial comparisons based on the games’ published setting and gameplay descriptions, not hands-on reviews. Mutable sale prices have been removed; use the individual official stores for current regional prices.
Choose by what you liked
How Fish Is Made is the free same-studio starting point for grotesque imagery and a compact narrative. Iron Lung shares isolation, confinement and first-person perspective, but focuses on piloting a submarine. SOMA is a longer first-person story about identity and consciousness.
Signalis shares space-horror imagery, puzzles and psychological themes, but uses an overhead perspective and a much stronger survival-combat loop. It is a mood comparison, not the closest mechanical match.
A separate upcoming project
Carcass Clad is Wrong Organ’s announced three-player PvE co-op game. It is unreleased and undated, so it is not offered here as a game you can already play. No sequel announcement was verified.
No exact playtimes, current sale prices or unsupported platform grids are repeated here. The stores below describe each game’s own supported platforms.
