What does the free demo contain?
Its own Steam page, app 4346510, describes a starting area, one dungeon and selected classes. The main game uses app 2411200. The developer’s initial introduction estimated roughly fifteen to thirty minutes depending on exploration; that is an early demo estimate, not a full-game completion time or a deadline for a careful run.

What has changed since the first version?
The September release announcement says the demo has been updated with many core features. Other 2026 posts describe expanded systems, improved feedback, additional character options and changes planned for the full game. Check what your actual download contains, since an update announcement and a feature available in every older build are not the same thing.
Does demo progress transfer to the full game?
The sources used here do not establish a general save-transfer guarantee. The demo’s Mushroom questline is said to return with changes. Keep its observations useful for learning controls and tactics, but do not assume that every item, quest state or character selection carries into a separate full-game installation.
