I think the main draw here is the soup generation that gets more and more complex and difficult to distinguish as the game moves on and in my opinion, it work incredibly well here. I was genuinely impressed by the variety of soup that was offered to me in my few runs throught he game.
The tradeoff, though characterisic for a game jam, is that there is hardly any gameplay to speak of. Probably influenced by the time constraints, this plays like a really cool tech demo and therefore, I think the mechanics and fun categories sufer a bit.
Overall a really nice entry and a very impressive demonstration of the concept, I hope you build something perhaps a bit more serious than a soupermarket from this concept!
