I'm not sure I understand how the progression is meant to work. At first I wanted to get a lot of stock to sell, so I explored a bit. But at some point explorations only end in Debug exits. I assume that might be because the inventory is limited?
It's pretty uncommon for customers to ask for something I actually have in stock, but when they do and I haggle correctly (which I assume means staying at or below standard price), I still don't gain any currency. They keep telling me they accept my offer and pay 0 for it anyways, lol.
From what I understood, it seems like only pressing Spacebar skips the scrolling text, which makes it more tedious to play with mouse only. It would be nice if there was a setting that auto-skips the scrolling text, or allowing held mouseclicks to also speed it up if possible.
Anyways, I wish you success with any future efforts!
