I played the build I made after I helped you fix your shader issue. It's kind of interesting. Once I started to get the hang of it I felt like a train conductor which was fun, but there was no clue that made it immediately obvious what my goal was. My main issue is that the game doesn't really teach you how to play it.
Through trial and error I was able to manipulate some of the levers, but there was no hint that in order to do so, I had to hold the mouse button down and move my mouse up and down to manipulate those controls.
