Is the Mouthwashing demo still available?
The Mouthwashing demo arrived for Steam Next Fest in February 2024, gained more languages in an August 2024 update, and is no longer listed. The full game shipped on Steam on 26 September 2024.
What I saw
I did not find a live demo button on the current store search described in the research log. The old demo app id 2747120 returned success=false from appdetails. I am not going to link a dead app id as if it still installs.
Timeline
February 2024: Next Fest demo. August 2024: a language update. September 2024: the full Windows release. By the 28 Oct 2026 check, store search returned the game, the soundtrack, and the free Work In Progress DLC, not a demo.
The exact day the demo was delisted was not in an official post used here, so that day stays blank.
If you wanted a trial
There is no current official demo to install. Steam’s refund window is the practical way to decide after a short session, and it is Steam’s policy, not a promise from this site.
The launch trailer is on YouTube if you want the tone before you buy. It is not a substitute for the game.

Questions
Can I still download the Mouthwashing demo?
No public demo download was found on the current Steam listing. The former demo API returns success=false; this does not test access for accounts that previously claimed it.

Steam Next Fest in February 2024.
Did the demo stay up after launch?
It is gone as of the 28 Oct 2026 check. The day it was removed was not found in an official post.
Is Work In Progress the demo?
No. Work In Progress is a free DLC name on the store, not the Next Fest demo.
How do I try the game now?
Buy it on Steam. Refund rules are Steam’s, not this site’s.
