This was really fun! Having the massive explosion of people coming out of the car and being able to shove them was a really smart addition. The AI was good too (though I think the entry door could have been a bit wider), and visually seeing the shelves get stocked as you put them in was satisfying, as well as seeing the customers walk out with their item. You nailed the game loop, I hope you add more to the game!
I also did a time-management game where you serve customers, I don't usually recommend my game when I leave a review but I think you in particular might enjoy it if these kinds of games are your thing :)
