5 stars all around. This game is really good! Really creative mechanic that gives you a lot of possibilities! I've beaten the main levels but haven't tried optimizing for score yet, the score calculation seems to make optimization a fun challenge as well.
Also super cool that you guys added a build your own word and share feature. I remember you did something similar for last year's jam and I think having some sort of sharing aspect for a jam game is incredible.
I don't have any constructive criticism besides things you've mentioned on stream like a being able to drag and rearrange + a recipe book.
There were a couple bugs I encountered though you might already be aware of them!
I got this error message as I disconnected a node I think (or it might have been deleting a factory type):

Rotating a Z should really count as an N :p
