Metal Mine 21The game
From one small worldto a whole galaxy.
Real-time, like the classic browser space empires: minutes at first, then hours, then days. All of it folded under your notch.
337,115
Mines and power
Metal a day on one planet, a few weeks in.
Expeditions
Fleets hold in deep space for hours. Some come home rich, some come home late.
Colonies
Pick an orbit by its climate and room. A cold world makes more deuterium.
The Market
Spy a rival planet once, then trade with it. Prices drift every day.
Moving worlds
Later on, move a whole planet to a better orbit. It keeps its buildings and takes the climate of its new home.
Why
Your workday is full of small waits.
A meeting that hasn’t started. An agent thinking. A file uploading. Most of us fill them with a feed.
With a feed

A feed never ends. You come back late, and scattered.
With Galaxyhold
tasknotchtasknotch
Queue an order, and there’s nothing left to do. You’re back first.
It runs out of things to askbefore you run out of time.
It started with my own waits. I work with coding agents all day, and every answer I waited for went to my feed. By evening my attention was in pieces. So I made a game that hides under the notch, is there in every app, and lets me go after a few seconds.
Your workday
A few seconds, a few times a day.
A day, a few weeks in.

Questions
Four times a day or once, it grows either way. Long expeditions suit rare visits.
It opens only when your pointer reaches the notch and folds when it leaves, without taking you out of your app.
Yes. Turn off Show Activity and Alerts and the closed notch shows nothing and sends no notification.
Your empire keeps time. Open the lid and it catches up, whether you were gone an hour or a month. Mines stop when their storage is full, so build storage before a long trip.
With the lid open it stays under the notch. Lid closed, it moves to the top of your main display.
The open panel does, like any window. The closed notch can stay blank.
Not measurably. In our test on a MacBook Pro, power draw was the same with or without Galaxyhold running.
Each empire lives on one Mac. You can keep several empires side by side.
Galaxyhold sits in a small pill at the top of the screen.
English and French. Spanish, German and Italian in beta.
$9.99 once on the Mac App Store, with no trial there. Refunds go through Apple, like any App Store purchase.
