I did not expect this to be as deep as it was! I liked that stats that you included for each item, and seeing the results of each customer was really cool as well.
I think you should include a little more assistance for the player for at least the first customer or two as I did feel a little unsure of the "right" items to buy despite completing the tutorial; I also see you included more directions on the game's page, which is great!
Nice job!!
