Thanks for trying the game! Your vision of creating an adventurer's guild and sending them to dungeons is quite similar to my original plan, but unfortunately, I ran out of time with not much content due to the node system taking a while to figure out.
I definitely want to add more content after the game jam ends and I clean up the code. I have seen a few other games with a similar node system as well.
My reasoning was that I wanted to learn how to build this kind of system for other projects in the future, but felt I was wasting my time on something I didn't need. Then the game jam theme was revealed and I decided it was the perfect opportunity to learn how to make the system, and get feedback to see if people would like a game using this system.
I like programming, but not everyone does, so I gamified it. A city builder could work, and I may consider it in the future. Thank you very much for the feedback!
