Once you press the green flag, the conveyor line will be disabled. You must flip the switch to the 'On' position. Once you have done so, the production line should begin to bring items along. There is no gameplay here, yet. I'm working on ideas. Use the Up/Down arrow keys to show and hide some settings.
I've meticulously commented all of my code to make it more understandable. I hope that anybody looking into the code will have an easier time from that. Recently, I've added some extra effects, such as a window with a sun and some clouds. When you stop the project, it becomes nighttime with stars. The conveyor operator also leaves for the night. Thanks to scratch for providing default assets for me to adapt!
