Beautiful visuals, and very chill 'gameplay' - I definitively see potential for more factory building. A little tutorial level or walk-through would probably be a good idea, took me a bit to figure out how to use the different things (was so zoomed in from the start, that I couldn't see the Cards to the right)
If you choose to continue work on the game, I'd suggest to leave the strict black and white, maybe just introduce 1 or 2 colours, that can really help highlight active elements, or point of interest.
But yeah, all in all I really like the concept
