What is in it

The studio describes a starting area, one dungeon, and some of the classes. They also say it is not a full preview of the release. A January 2026 post puts the length at 15 to 30 minutes. In September 2026 the demo was updated with most of the core systems that the full game uses. It includes the same seven languages and cloud saves.

What the reviews said, as of 5 Nov 2026

Steam showed 387 demo reviews, 97% positive. The recent slice was 67 reviews at 91% positive. Those numbers move. I am quoting the reading from 5 November 2026, not a live ticker.

What is still blank

Whether a demo save carries into the full game is not announced. I am not inferring a yes from the shared cloud-save label. Which classes are missing is also unnamed: the post says “some classes” and stops. As of the check date the demo was still listed for download. I do not have a sentence that promises it stays up after launch.
