AURUM

The Great Work
Base matter, made gold; night, made dawn.

A physics merge game. Substances fall with true weight into a glass vessel; two of a kind, met, glide together and fuse into the next and rarer form: eleven forms, from Moonstone to living gold. Every union sings, and the work you do is written into the sky.

The Craft

Every law in this vessel was written for it.

AURUM does not use its engine's physics. The matter is solved by code written for this one scene: a hundred steps a second, with fourteen more inside each of them. The reason is one your eye can check: every substance is painted exactly at the edge the solver uses, so any compromise inside it would be a visible lie.

True weightMass follows size. The largest form weighs about a hundred times the smallest, and the pile beneath it answers as though it does.
Nothing snapsTwo of a kind glide into one another, their haloes bridging into one band of light, and only then resolve into the next and rarer form.
A settled pile is stoneRest is what the eye calls rest. Once matter has come to rest, nothing here trembles.
Drawn, never boughtNo art files. Every substance, vessel and star is drawn as you look at it, by shaders written for this game.
The Night

Keep the work below the brim.

Matter falls where your finger asks. Three rare reagents fall now and then, the alchemists' tria prima: Quicksilver raises what it touches by one form, Sulphur leaps it two in a blaze, Salt dissolves it back into Essence.

And one real decision runs through every night. Working the vessel heats it: heat rises only while you are truly merging, and faster the nearer to the brim you dare. Pour it off and bank it, or ride it and lose everything the night has made.

The Great WorkSixteen designed stages, each one a named star.
EndlessOpened by The Draw: three sealed vials, one kept. Every gift carries its stated cost.
DailyOne seed, taken from the date itself: tonight's matter falls the same way for everyone playing tonight.
ZenNothing ends the night but your own hand.

Only the first five ever fall. The rest you have to make.

The Resonance

The melody leaves its chair empty for you.

Every union plays a note. The eleven forms are eleven degrees of one pentatonic scale, chosen so that no cascade can ever sound wrong, and a chain climbs the scale as it grows. The note does not sound the instant matter meets: it waits, to the sample, for the music's next grid line, so what your hand makes lands in time with the piece that is playing.

Six pieces were composed for AURUM and travel inside it. While you play, each piece empties the chair of its own lead melody: the written line falls silent, the accompaniment thins, the bed plays on, and your merges, already in the key, already on the grid, take the seat. When the night ends the piece returns whole, and the record turns to the next.

Three notes carry the whole signature: base matter, noble, gold. The phone taps the same three in your hand.

The Sky

As above, so below.

Eleven substances, and eleven stars. The first time you forge a new matter, a spark leaves it, climbs and ignites as a star, which then burns in that substance's own colour behind every screen of the game, for good. Beneath the horizon a dawn deepens as the Great Work advances, so the night itself warms while you work.

The campaign is that sky, not a list of levels. Sixteen stages are sixteen stars in the four constellations of the Magnum Opus. Clear a stage and light travels the connector to a star not yet born, which arrives in a white strike and settles into its chapter's colour. Complete a chapter and the figure is drawn, and speaks.

The Raven · the BlackeningFirst into the dark went the raven, and the dark gave up its first pale gleam.
The Swan · the WhiteningThe swan swam the long white silence, and taught the matter to hold the light.
The Peacock · the YellowingA hundred eyes upon its tail, and every one of them the dawn, rehearsed.
The Phoenix · the ReddeningIt does not survive the fire. It is the fire: rising, crowned.
The Promise

No ads. Ever.

Not a policy that could be revised later. There is no advertising code in this game and no advertising library in its manifest; the one seam that could ever have carried one was deleted rather than left switched off, and an instrument in the workshop checks every build for both.

What money buys is look, sound and identity: beauty, never power. Every ability that decides a night is earned inside that night. Nothing sealed is ever sold. And what you buy, you then raise: a collection matures through play alone, and nothing can hurry it. You raise a companion; you do not buy a skin.

Any collection may be worn free for a single run, once ever, before you decide.

Begin the Great Work.
