You keep a colony of little duplicants alive inside an asteroid, managing oxygen, heat, power, food and plumbing. It's a cute cartoon wrapped around a brutal physics sim.
Kit's verdict · 8.9/10
A colony sim that teaches you thermodynamics by letting everyone suffocate first.Kit · Sadkitty Games
Loved
- Deep gas, liquid and heat simulation
- Charming art and duplicants
- Endless engineering puzzles
Not so much
- Brutal learning curve
- Late-game colonies slow the game down
Play it if engineers, tinkerers and Factorio fans.
Skip it if players who hate failing and starting again.

Tips
Play it better
- Build Algae Deoxydizers or an Oxygen Diffuser first, and move to Electrolyzers once you have water.
- Carbon dioxide sinks, so dig a deep pit or put a CO2 scrubber at the bottom of the base.
- Build Outhouses and Wash Basins early to stop food poisoning germs spreading.
- Keep food cold, or better, store it in a sterile carbon dioxide pool so it doesn't spoil.
- Pick duplicants with good traits, and reroll printouts rather than taking a bad one.
- Watch the heat overlay, as machines slowly cook your base if you ignore them.
