STEAM NEXT FEST DEMO — Revist Quill's Story in a New Perspective 🐭

Hi everyone!
As part of Steam Next Fest, the demo for Moss: The Forgotten Relic DEMO is now available to play!
For those who may have missed the announcement, Moss: The Forgotten Relic is our reimagining of the Moss adventures for PC and consoles. It brings together the stories of Moss and Moss: Book II into a single experience built specifically for handheld (✅ Steam Deck Verified!) and flatscreen play. It's launching July 16, 2026!
The heart of Moss remains the same, but the experience is intentionally different with new camera systems, updated controls, and enhancing performance and visuals.
For many players, this will be their very first opportunity to meet Quill and experience her story in a medium that is available and comfortable to them. We're excited that more people will finally be able to join the adventure, and many will have the chance to revisit an old friend in a new way.
What to Expect in the Demo
Around 30 minutes of spoiler-free playtime
Meet a tiny hero that happens to also be a mouse
Exploration across handcrafted, diorama-like biomes
Environmental puzzles woven naturally into the world
Light combat encounters and interactive traversal
A few secrets along the way
HEAD OVER AND PLAY 🐭❤️

There have been a couple of patches following our latest big update to Moss. Here are the details:

Last week's update was a full rebuild in Unreal 4.27. This was the reason for the large download size.
In the time since the last Steam release, the game's project was renamed from "MossGame" to "Moss". The patch on Oct 19 included an engine change to force it to continue using the name "MossGame" when looking for save data. Save files which appeared to be deleted were not removed and are now visible again by the game. For those who may have started a new game before the Oct 19 name fix, that save data is located in %LOCALAPPDATA%\Moss\Saved\SaveGames and can be transferred to %LOCALAPPDATA%\MossGame\Saved\SaveGames. It is recommended to make a backup of the destination folder before replacing any files.
Old configuration values, in particular those related to input, were getting stuck in cached engine configs. The most recent patch contains a small update to input configs and the default launch option now includes the "-regenerateinis" command line to force the engine to update these cached configs.
Thank you to everyone flagging issues and sharing workarounds in the discussion boards.

Crash fix for Intel Tiger Lake processors
There was a crash on launch for users running with Intel Tiger Lake processors. This was due to a bug in the OpenSSL code used in the 4.21 version of Unreal Engine (the version of UE4 that Moss shipped on). This was fixed in UE4.22. We folded in the updated SSL library into Moss.
