Good on theme, a bit hard on the gameplay.
I understand the idea behind it, but as far as I know it is impossible to see how much you would sell a certain item for. My tactic was just buying the cheapest thing and selling it as much as possible whenever the category got mentioned but you can't simply wait for the category to get mentioned because the items on your shelf will drain your money insanely fast.
There surely is potential in this kind of game if the rough edges get polished.
I managed to get about 2000 BigShotness which got me a nice quote from Indiana Jones :P
Great job on submitting to the jam,!
