This is a cool little demo. I made it 16 hours. There were a few turns where I accidentally clicked / committed to a bad trajectory though, wasting an absurd amount of delta v. The interface was pretty easy for me to use as a KSP veteran.
Is the tech you're working on in orbit_tesselation intended for another game idea? I'd be interested to know where you're going with this, or other projects using the same tech. Any plans on packaging it up in a way that doesn't depend on a specific third party bevy crate? I've got a backburner project that could potentially benefit from an easy-to-use orbital mechanics plugin.
