I managed to find some time to watch!
Definitely going to add a more visible sign, and maybe a few other details while I'm at it, to the potion shop in the upcoming update. (It's the one in the northwest, next to the blacksmith shop.)
As far as the UI goes, I have a few ideas as to how I'd improve it, and I'll likely implement these shortly after the aforementioned update.
Thank you again for playing Ruphand: an Apothecary's Adventure!
