Play before launch

The Steam demo is the verified starting point

What the demo includes, what it can teach, and where its answers stop applying to the Early Access build.

01

Use the demo to learn

  1. 01

    How Explore cards change movement and route choices.

  2. 02

    How Combat cards, energy and enemy intent feel in practice.

  3. 03

    Why Rest and Gloom turn redraws into a strategic cost.

  4. 04

    How roasting and eating connect exploration resources to survival.

02

Do not assume the demo is the final rulebook

A demo can preserve older balance, content, save behavior, or card text. After the Early Access build is available, this site will label demo-only observations and recheck pages whose advice depends on exact rules.
