How it feels

A precise, educational tool that feels like methodically plotting orbital paths through a photorealistic solar system.

What players say

Players see it as the closest thing to a KSP successor, though it leans heavier on simulation than the original. It relies on automated launches and real-world orbital mechanics, which makes it rewarding for experienced players but very challenging for newcomers. Reviews note the tutorial is thin, but the developer is actively updating.
