Great stuff, great start. Controller works well. I'm a big fan of "scales" trading UI, and not a big fan of "numbers" trading UI. Dialogue during trades needs to be either skippable or faster, cuz I kinda expect the trading window to close after the trade is done.
Sprites are cute, and the newspaper telling you current market situation is a great way to give me a heads up. Running out of sellable items feels almost like a softlock, but I understand that it's still WIP.
Shop customization is VERY welcome, and I'm curious to see how the "shop type coordinates" affect the customers.
Can't bash the littering customers with my broomstick, 0/10
Keep it up!
