Sources and Evidence
Every factual guide on this site is tied to the official Steam listing or a developer announcement. Source IDs identify what each page used; they do not imply that this site has tested the game.
Primary sources
S01 supports the product identity, store-described game systems, listed languages and PC requirements. S02 documents the actual playtest opening and key route. S03 is a dated development plan. S04 answers specific design questions, many of which concern future builds.
How claims are labeled
“Confirmed” means an official page directly states it. “Planned” means the developer has announced an intention, but the date or feature can change. “Unverified” means the cited material does not establish a result in the current test build. The site does not turn store copy into a hands-on review.
Known gaps
The research record was checked on 2026-11-12. Corrections can be sent with a direct source link and the affected page URL.
- Live key supply and Discord channel instructions can change.
- Exact Early Access day and version 1.0 date have not been announced.
- Detailed quest paths, equipment values and build rankings need build-specific evidence.
