Glad you liked the idea. Yeah the 3 npcs are all there is and rest is empty. You do get rewards, you do the card thing to reduce effort and accept task, then interact with the task object and then talk to the NPC again. I need to make that more clear to the player. I'll be adding more content and polishing the game soon after the jam. Will let you know once done.
Thanks for playing. Appreciate the feedback.
