About

Sulbio

We publish field notes from the edges of indie gaming — quiet, strange, and deeply imagined worlds that deserve more than a review score. Each entry is a map, a diary, and a guide rolled into one.

Field Report

Frequently Asked Expeditions

Answers to the most common inquiries received at the Cartographer's Society.

What exactly is The Wandering Index?

It is an exploration game about documenting a world that resists mapping. You play as a traveling archivist, collecting fragments of local myths, architectural curiosities, and fading dialects. No combat is involved—only mystery and the slow archaeology of a place's memory.

How long does an average playthrough take?

The primary narrative arc can be followed in four to six hours. Completing the full Index—discovering every hidden footnote, optional ruin, and marginalia—typically requires twelve to fifteen hours of attentive, unhurried exploration.

Does the game have combat or jump scares?

No. The Wandering Index is a pure, pressure-free experience. There are no enemies, no fail states, and no jump scares. The world is indifferent but never hostile, and the only risk is leaving a story untold.

When and where can I play it?

The full game is in development for Windows and macOS. A free, self-contained prelude called The Vestibule is available for download right now, offering a first glimpse into the world and its systems.
