Thank you for the feedback and for playing the game!
The next version of the demo is going to have a checkbox that lets you autosell crafted items, but a shopkeeper fox does sound like a great idea, I'll think about somehow implementing that.
I think bulk selling gear would be a great improvement, or just a shortcut to sell with a single click. Sometimes you want to craft a lot of gear to get one with good stats, and that can take quite a few tries with the random stats. But that means you want to hold onto them enough to check the stats, rather than auto-sell them. To a lesser extent, gear you find in combat can be a little tedious to sell if you leave it idle for a while.
Game's still fun, though. It feels like you actually use more features, even if maybe the buffs you get from potions, food, and party members aren't particularly high.
