I like the idea!
The tutorial was a lot to take in all at once, I think it would be easier on players if you just gave them blocks to build stuff with instead of showing them an already completed machine and explaining how the parts works via text.
I understand that you want people to get automation right away but one of the reason tech trees exist is to stagger that information as the player progresses through it.
It would also be nice to have a clean slate world to experiment with and experience a normal start.
This demo is light on actual gameplay so it's hard to give feedback on the game proper, but it does look like it's going to be fun.
