I think for all but one potion, instead of giving you the list of what you need, it just skips ahead if you don't have the ingredients needed. I also don't know what the third potion is about, if it's just not implemented yet.
And after the first time I talked to her, after which I think I used a potion, I never managed to talk to her again without getting looped endlessly.
It also felt like streaming earnings didn't improve much at all from reading. And I'd have expected it to improve with potions as well.
Interesting concept so far, looking forward to updates.
(Also, it would be appreciated to know how many ingredients you actually have at a given time.)
