Worth buying? What 300 Steam reviews say.

Overwhelmingly Positive2019

The verdict

A deeply complex, rewarding thermodynamics and colony-management puzzle with endless replay value. Skip it if you want hand-holding, a chill builder, or dislike looking up guides.

Great for

Players who love systems engineering, problem-solving and learning through failure, Factorio/RimWorld fans

Main risk

Poor tutorial and brutal learning curve mean many players feel forced to watch guides and restart repeatedly

What players love

Deep, consistent physics and systems

Mentioned in ~1 in 5 positive reviews

“Gases, liquids, heat, power and automation all run on rules that stay the same no matter how chaotic the colony gets, so when something breaks it's always your fault, never the game cheating you.”
