Just a comment here to help some new players since the ingame tutorial is a bit vague. The goal of the game is to get everyone the thing they want. It's basically a mini questing system. Some NPC's need to be interacted with multiple times to finish a conversation and some conversations won't appear until you have an item that interests them.
Pressing 'E' to open your inventory is very helpful for checking what items you have and what quests have been assigned.
This is something I had hoped to clarify/correct in game, but didn't have enough time to properly explain. Thank you for all the feedback, it is very helpful and gives me some key points to keep in mind when working on future projects! :)
