Just a few quick notes on NPC interactions based on my current experience.
Is it possible to add a highlight (the white border) on interactable NPCs just like it happens for chests and breakable objects currently. Mouse over → Highlight the NPC.
For NPCs that do not really have anything to say but act as a “shop” could you directly open the “shop” interface instead of going through the chat popup and selecting the proper action.
Not big things but would perhaps improve the UX.
Thanks for a good game <3
