Just finished the tutorial in the demo, and it's such an awesome system you've designed! My only wish is that there are gameplay elements that exist outside of just progressing through the tech tree, to justify building such complex factories. By the time I had figured out a way to automate a material for research, so much trial-and-error had happened that I was over halfway there, so I didn't feel the need to go back and find quicker ways to make things.
I'd love to see this kind of system used in more games though, it's like combining all the best aspects of other factory/sandbox games into something approachable but challenging
