Fun concept to mess around, a bit sad for me that this doesn't have any objective to clear aside just build and mess around in the factory, which after a few minutes the fun ended for me. But it fits the theme of the jam.
You can put objects outside the factory and overlap them. My old PC started to lag after spawning a lot of cars so it was fun to see. I liked how fast the objects can go in the transport bands and I liked the visuals and the little song, it fits together.
Good game for your 1st jam. :)
