It's a peaceful and laid-back kind of industry/crafting/management/whatever game. The crafting UX is one of the worst I've ever seen and the exploration aspect is extremely limited for a "space exploration" game. Once you fully explore one planet you've basically seen all of them. The only thing that changes is the terrain generation itself, which does give every planet a unique visual feel and a somewhat unique way to be traversed. But in terms of what you're actually doing, which is collecting resources and building a factory, every planet is exactly the same. The only thing that changes is the color and name of whatever resource is semi-unique to that planet.
I'm still giving it a 3/5 because that one thing you do is very fun and all the little toys you get to build along the way are fun to play with too. It's a shame that they're basically useless outside of some fetch-quest.

I'm gonna go ahead and say that I completed it even though my brother blew up our very important item storage and may or may not have bricked our save, shortly before stranding us somewhere else by clipping our ship into the void.
I don't get why people say this game is good with friends. Maybe we were playing it wrong, but to me it feels like it would be the perfect game to play while listening to a podcast or music or some random 3 hour long video essay.
