This is a really cool idea! I like work sims like this. The vibe is a weird (but good!) mix of relaxed and high-pressure.
The amount of calls coming through with different instructions was overwhelming at times. This might be better conveyed through some kind of visual display. It would also help to be able to just press a dedicated button to switch directly to each of the three spots instead of a left-right cycle.
Really fun overall! A hidden gem in this jam to be sure.
