I really like this take on the whole trust no one theme! Shopkeeper sims are not necessarily my jam, but I did like the concept and theme. Art style is also very much a vibe, good job!
It took me a minute to realise I had to actively sell my items to people. I also wish I could be holding the items I wanted to sell and choose to buy an item off of someone without having to put stuff down. Maybe its cos of moonlighter, when I saw the tables I thought that's how I would need to display and customers would just buy them from the display :D
