Customer reviews
Our research team analyzed the air composition daily for a month. Oxygen levels, trace gases, humidity—all within promised ranges. Legitimate terraforming.
It's fine. The floating island world is interesting but the gravitational instability makes some areas difficult to develop. Not what I hoped for.
The ecosystem maturation took longer than expected. Once stable, everything performs excellently. Recommend if you can wait for stabilization.
