I love the concept! Having to keep track of both screens and memorize what each passenger had at any point provides a really interesting skill challenge. Gave me a Papers Please vibe with how you get to decide each passengers fate based on what you know about them.
Maybe something to improve could be a more clear indication when a new item is scanned. As it is now, if 2 passengers in a row both have the same item, it can be a bit confusion whether or not they were actually scanned. Also some direct player feedback to see if I did good or bad when making a choice would be nice!
