Such a nice vibe overall! Loved the visuals.
The gameplay loop(literally) is a really fun experience at first. After reading the comments I saw the difficulty curve bug... after all it is a jam, so I really loved the mechanics already. Got to 150k before the game eventually became a bit too unchallenging to continue, but it is still really fun carrying the luggage around!
I know that this is only a 4 day jam, but just a small suggestion (for a possible post jam version?) could be to spawn in a number of customers already with distraction choices to increase the difficulty. Because that each box directly correlates to one customer, I don't have to see what luggage they need lol.
Great job!
