This week
A small universe of its own, for this week only. Build it with Flux; its rewards come as you go, and next week it begins again.

How to play
You are running a universe forward from its first instant. Tap the core to gather dust, spend it on the timeline above, and each thing you build makes the next one reachable. The clock at the top is how far into the universe's life you've got.

Your universe is saved on this device either way. An account syncs it between devices and lets you add friends. Nothing about the game changes.

Settings
AppearanceDark is deep space. Light re-draws the same timeline as an astronomical chart on paper. System follows your device.
SoundClicks, purchases and event cues. Synthesised — there are no audio files to load.
AmbienceA quiet drone under the game that deepens with each epoch. Off with Sound.
VibrationA short buzz on a tap, a purchase and a milestone. Phones that can vibrate only.
Anonymous statisticsCounts how far new players get — the first tap, the first purchase, each epoch — so the start of the game can be made better. No account, no ID, nothing about you: only a tally per day. Off stops it at once.
Show the opening hint againBrings back the tip that explains the core and your first purchase.
Move this universeProgress is stored per-website, not per-device — copy a save code to move it somewhere else, or sign in above to sync it automatically.
Start overErases everything on this device — dust, structures, Seeds, the codex. Not the same as a collapse.
Shop
Cores, palettes, lines, titles and two small comforts, bought with gems. Boosters are earned in play.

Collapse this universe?
+0 Seeds
Everything you've built returns to potential — dust, structures, this epoch. The seeds carry forward as a permanent head start on what comes next.
Carry one constant forward
Its multiplier survives the collapse. You will own none of it — but the first one you buy in the new universe is worth that much immediately.
Make it a challenge
Optional. A handicap until its goal (Epoch 5, unless it says otherwise), then it lifts, and the reward is yours for good.
The next universe's law
Optional. Each one is a trade, and the universe that runs under it pays the Seeds side itself.
The timeline forks
Divergence
This universe, and a gift to the next
Taking one path closes the other until you collapse. Collapsing opens it again — the road you don't take is waiting, not lost. Collapse on the deep road and it leaves half an hour of Charge for the Fine Structure; on the swift road, half an hour of Light for the Firmament.

Paste the code from “Copy save code”. The universe here now is kept as a backup first.

Everything
This erases all of it — dust, structures, Seeds, the codex, every achievement. Nothing carries forward. Unlike a collapse, there is no seed left behind.

Share of your income
Pays back in: how long one more copy takes to earn back what it costs. Shorter is better value.
Refinements
Each one: more from what you own, or prices that climb slower — for a node you'll buy a lot of.
