We actually had a similar idea at first! Glad someone else made it. The art is beautiful!
I would have definitely liked more variety quest-wise, and probably fewer parameters (they were kinda difficult to track, and I believe the mechanic could have worked as well without most of them). I am thinking of a three discrete system with quests that get randomized requirements. And maybe make it so the adventurers get stronger over time.
Looking forward to the upgraded version you mentioned below!
