This game is very good! It's a bit frantic at first, but it's nice when you get the hang of it. (I had a noticeable tendency to verbally say what I was commanding each staff member to do, lol) The art is amazing and so is the music.
If you're looking to continue working on this, it would be nicer if the deliverers automatically gave the boxes once they reach their destinations. Also, perhaps there could be a route system so you could assign a person multiple spots to go to. And it would be better if the train on the bottom left island connected to the right island so it would be more useful.
Overall, really polished game! Great job!
