Agreed with MythAcre, I like the idea of the game but it feels a little underdeveloped. Perhaps you could limit the amount of inventory you have to sell each day, and then get a store where you can spend the money in between each day. There's also no indication of what prices are acceptable to customers, so perhaps you can use a scale of like, smiley face to frowny face, to describe how willing customers are to buy each item at each price
