Fill the Sky

Land. Build. Launch.
A probe settles onto an empty island beside an ocean, carrying little besides the knowledge of how to build.

Begin with scraps, build a massive factory.
You are the mind of a self-replicating interstellar probe. Start small: mine,
smelt, assemble. Then learn to build the ships that will carry copies of yourself to the stars.
Technology shapes your factory
Belts, ships, pipes.  Then mass drivers to relieve spaghetti (if you choose).
Engineer in peace
No enemies, and no clock.
Night falls, the stars come out and smoke drifts across the landscape. Photo
mode captures it all.
Find the bottlenecks
Hold a key and the factory shows you the slow areas: full belts, starved
machines. Trace and fix the issues. Upgrade.  Save optimized blueprints and use them to expand quickly.
Watch it over and over.
Open Rewind and watch a time lapse of your factory from the first miner to the last launch.
Speed up, pause, use the camera to roam freely.  Jump to any moment and restart from that point.

The first launch is only the beginning.
