Nice hand-drawn art and fun dialogs with the characters. This is a fun concept that, although reminded me a bit of the game “Overcooked!”, I could see this being a fun mobile game where you become rich (or lose everything), based on having to learn which type of characters want which types of items, and figuring out the best way to price things, and then you could upgrade your shop to unlock different items and power-ups, etc, etc. 

A few issues I ran into: The buying screen was a bit confusing, since there are question marks in some places, and because prices don't have dollar signs. At one point, I bought 4 arrows from a guy for $13, then placed them on the table and he immediately bought them back for $15. Sometimes I can’t click on an item right away when I’m trying to place it on a table. It takes a few seconds before I can interact with it.

Overall, nice job! I'd love to see an expanded version of this some day.
