Make a Remix of this project to continue creating your own. This starter project begins with a empty shop backdrop and one salesperson sprite with 4 costumes and "green flag clicked" initialization code. Your task will be to create an interactive storefront for your business by adding sprites of your product and having the user select what to buy. You will use broadcast blocks and a My Block with parameters to do this. You will also create a variable to tally the customer's purchase total and use the "join" operator block in a Say block to share the amount with the user.
