Something waits at the end of the chains.
A black energy wakes in the dark, and you route it through the links until the golden seals burst. Every chain has a shortest path. Finding it is the game.
How it plays
Route the energy. Burst the seal.
A chain is a circuit of fixed links, rotating pipes and valves. Black energy floods everything you open to it. Golden light runs the other way, out of lanterns, guards and the seals themselves, and where the two meet the larger number crosses and keeps the difference. Equal numbers lock, and nobody moves.

Gameplay
One chain, start to finish.
No cuts and no edit: a chain from the first tap to the seal breaking, at the speed it actually plays.
Captured from the build, unedited.
Moves and best
Solved is not the same as solved well.
Every chain counts your moves and remembers your best. Clearing it is the first question. Clearing it in the fewest moves is the real one, and the three seal shards go to the player who reads the whole circuit before the first tap.

Ten chapters
Ten places, and the last one is not a place.
Every chapter is twelve chains in one part of the prison, with its own art and its own demon behind the final seal.
The vault vestibule
Angel chains, locks and seals, and one link that is already broken.
The kennels
Whatever was kept down here was kept in rows.
The forge
Where the chains were made. It has not gone cold.
The rail yard
Everything moves on its own axis, and everything is in something else's way.
The gallery of copies
Mirrors. What appears on one side has an original on the other.
The sealed doors
More lock than chain.
The gear gate
Rings and gears, and none of them turn alone.
The crypt
Quiet, and not empty.
Black glass
The floor shows you back to yourself.
Kraavos
Not a room. The map is his body, and the twelve chains are the points where he is held.

The legion
Every chain you open frees something.
Behind the last seal of every chapter is a demon, and freeing it does not send it away: it becomes a power you spend inside a chain. The Brute bursts a link in one go. The Guardian drops a black shield that stops the light and lets the corruption through. Vharok makes the copy appear in the mirror. The Colossus brings the rock down and shows you the link behind it. The Devourer takes a shield away. And one of them will light a torch when nothing else will.

The centre
Something enormous is still chained.
Ninety nine chains run outward from the dark in the middle of the map. The hundredth runs inward. By then you will want to know what you have been doing all along.
Release
Know when the seals break.
One message when Void Myth is out, and nothing else, ever.
