I really like it, especially the 3d modelling and general feel. It's just way too much stuff to take in and think about at once. Honestly if there was only one of each machine type, and they were all separate from each other, and the room was much smaller but not too cramped, it would be less overwhelming and easier to play.
I don't know if the powering machines thing was even working because they all seemed to work fine without being plugged in.
