About This Game

"Go now, Lityria. This is the path you chose."

Four hundred years ago, six hundred people left Earth.

Their ship is still out there, somewhere in the middle of the crossing.

They are still asleep — and what they are seeing is a single shared dream, managed by the ship's AI.

The world has been replaced many times over. With each one, they have lived as someone else, an entire life at a time.

This is the last of those dreams.

Lityria sets out remembering nothing — not even what it is she has forgotten.

Driven by a restlessness she cannot explain, with two companions at her side.

Twelve labyrinths lie scattered across the world, and at the bottom of each is a key to the seal that holds it shut.

Every key she recovers returns a little more of who she used to be.

A story about a mother and a daughter, told across an enormous distance in time and space.

Twelve labyrinths, twelve pieces of the truth

Find and clear the twelve labyrinths scattered across the world, and the shape of this place slowly comes into focus.

Why are we here?

What is waiting at the end of all this walking?

And when everything is finally clear — do we still have to go?

Gear you grow by exploring

Ore and gemstones found in the field and underground are what make your party stronger.

• Swords and bracelets evolve across ten elements and four tiers — forty variants in total

• Higher upgrade levels raise more than attack and defence, boosting a range of stats

• Progression comes from walking the world, not only from winning fights

Every new skill opens the map further

Offer Crystal Stones at the goddess statues scattered across the world to learn magic and sword arts.

Clearing a labyrinth unlocks traversal abilities — shattering rock, crossing elevation, moving machinery, clearing blocked paths. Places you could only look at become places you can reach, and the world keeps widening.

380 hand-built maps that change as you travel

Dawn, midday, dusk, night. Clear skies, light rain, storms, blizzards.

The landscape shifts constantly with the hour and the weather.

Underground rivers and lakes, ice caves, lava flows, crystal caverns, total darkness — every region hides something different below it, and at the end of each waits a labyrinth with its own theme and its own puzzles.
