Seems like you're off to a good start!
It took a while process what was going on in the scene since it's mostly placeholder tiles but all the interactions made sense.
I haven't played recettear, but I really liked Moonlighter so I might be biased when I say I liked being able to price items when they're placed on display over haggling each individual at the counter. I guess it makes more sense to haggle when buying from people who walk in tho.
Played about 20 minutes with controller, only ran into one problem when the controls locked up (might've been out of stuff to sell, unsure, I just sold a bible at 120% which was the first time I changed the decimal value)
(You should change "pie cookie" to "cookie pie" cause it sounds cuter ;)
Good luck on your game!
