Thanks!
Dryad + Other NPC scenes are on the way. Adding them a little at a time. Still a bunch left to add for Lucy, Scout, and Ellie as well. There will be a variety of scenes, but I don't really have a planned list. I'll just keep adding scenes as I have time.
When you are in fall (in the current build) you buy items in bulk. There may be a toggle later on as well, but the way you interact with merchants is intended to change as the game progresses.
