Sunderborn

Sunderborn is a logic-driven strategy puzzle in which you transform Chaos into primordial elements and use their relationships to shape a world of your own.

In each Seed, seven elements are hidden. Decipher their positions using the clues, while respecting elemental oppositions: Fire and Water, Life and Death, and Astral and Mind cannot sit next to one another. The puzzle is about reasoning through these constraints rather than guessing.

The free Steam demo is available now. We are especially interested in honest first impressions from players who have not tried Sunderborn before: play for roughly 15–20 minutes, then tell us where the rules feel clear or confusing and what makes you want to continue (or stop). A screen recording is welcome but optional; written feedback is equally valuable.
