Super cool game! Loved the color palette choice. Artstyle is great. Sound design worked perfectly for the game. The movement was quite fun. Quite the novel idea as well!
One critique and change you might want to consider is:
I didn't really feel the tension during the game with the timer implemented the way it is right now. There wasn't a sense of being close to failure or failing until the timer actually ran out. It's a long time to go during the game without feeling any sort of tension. Maybe consider having a timer for each individual customer. If you don't deliver them in time, they get angry, disappear/leave somehow, and don't count towards the people count. This makes the tension felt during each delivery and a sense of urgency to complete each one instead of one long drawn out timer.
It's just a suggestion, not a definite fix.
Overall a super great game! Enjoyed practically every aspect of it.
