Demo availability
The playable build is the free Abyssal Lapidary Demo (app 4736580), live since 16 Oct 2026 during Steam Next Fest. Store review label on that date check: Very Positive (~87% positive — Steam counts move; verify on the demo page).
Official Next Fest FAQ: the demo offers 4+ hours in a single playthrough, covering roughly 25% of the full game (Steam announcement). It is a short workshop day-loop, not the finished campaign.

How long will the demo stay up?
Steam has not announced a takedown date in the posts we cite. If that changes, it will show on the demo store page or official news — we will not invent one.
