Eh, idk. Looked up "Arrokoth" which turned up nothing (a minor annoyance, being a big fan of the dented peanut rock), and the planets seem to have some texture artifacts as well as just a level of blurriness that shouldn't be possible if LOD is being applied (there are high-res images of many of these objects I'm pretty sure, surely there's high-res textures too?). Scale seems aight. Controls are atrocious. GUI is almost unreadable. Not sure if this is unique to WINE. I'd ask for the source but I don't, can't and won't use Unity.
