The main character and city design are gorgeous!
I like the haggling system, but found it rather frustrating, as it's a bit hit-and-miss. Plus the MC tended to be somewhat discourteous. The addition of extra dialogue options as the game progresses is a nice touch, although many of them drove potential customers away right from the start. I tried to pay close attention to the descriptions when first approaching them and did see some interest, though "negotiating" too much still caused most of them to run away without a sale. If you can tweak the haggling system and dialogue, this would be a great game.
The overall concept of the game is quite fun and funny. Any form of humor - whether subtle or overt - is a good thing.
Thanks for submitting this to the game jam!
