Description

High RPM or high torque? Tinker with gear ratios to pursue efficient power transmission.
Run short on power and your machines grind to a halt. This is hands-on, physical engineering you can’t get from simply connecting wires.

From waterwheels to steam engines, electricity, and fusion. With every leap in technology, what you can do expands.
Automate everything from mining and smelting to processing and assembly—build a production network where materials flow on their own.
Your ultimate goal is to build a rocket. Develop your factory and aim for a return home.

Yori (left): The second princess of planet Celestal. Exiled to planet Arcadia without even knowing why. She starts out as a sheltered young lady who can’t do much, but with Ereno’s help, she pushes industrialization forward.
Ereno (middle): A general-purpose support AI system who came to planet Arcadia with Yori as her attendant.
Kurua (right): Athletic, genuinely bright, and easygoing. Friendly and chatty. She loves money—and will do anything to survive.

A complete step-by-step tutorial that teaches the fundamentals of factory automation.
No more “I don’t know what to do next.” Your companions will guide you toward your next objective.
Veteran players can skip the tutorial and jump straight into serious construction.

Create mods with a dedicated editor—no coding required.
The game’s full source code is publicly available on GitHub.
