I'm a sucker for automation games, but this one didn't really pan out. It's another lesson in Early Access - it's often not worth it unless it's from a studio you trust. I backed this very early on, then the developers started working on laser tag... in a factory game. Development was basically dropped before the game was finished, and rushed out the door as a 1.0. The game was always poorly optimised and instead of fixing that, the studio decided to break the large world map up into tiny floors in the 1.0 patch to hide it. If you're looking for a 3D factory builde, go play Satisfactory or Dyson Sphere Program. Better still, go back to Factorio again.
