Hey thank you for taking the time to try our game and leave a comment, I'm glad you liked the visuals and music (We'll be adding more later). The longer you are in the store the more customers will enter and it should get out of control pretty quickly adding just the right amount of chaos.
The shopping list actually changes with each playthrough as does the products placement, we'll probably add a visual indicator when you get close to something that's on your list to make it slightly less chaotic finding your items and allow more time to focus on avoiding other shoppers.
