Wow...What a great little title and there is so much room here for things to expand on. One of my favorites for this jam. The music was sooooo nice. The controls and mechanics are great and easy to get even without a tutorial. People in my town booze way to much :) I was buying red boxes like crazy and couldn't keep up with demand. My only issue in this near perfect jam entry would be that the office door could be more clearly marked (maybe a hanging sign idk). 1st play I though the store room and office was the same room.
Bonus Idea - 4 player multiplayer (Cashier, Stock boy, Buyer and floor staff), or a single player mode where you jump between jobs. Just an idea
