Very astute observation! Indeed, I was already interested in building a node system but felt I was wasting time. When I saw the game jams theme of "Connections", I figured it was my chance to learn how to build this system, and get feedback to see if players would be interested in a node-based game.
I didn't have much time to add content as I was focused mainly on getting the "feel" of the nodes right, and the system was quite buggy at the end. I am currently rebuilding the system to be able to efficiently add content in the future.
While the audience for the game jam is primarily developers, I understand that the results are biased, but feedback has been generally positive, with the only criticism being the lack of content which is completely understandable.
I am focused on making the system as intuitive as possible to be accessible to people with no background in programming or node-based software, while being open enough to allow more experienced players the freedom to choose how the want to play the game.
Thank you very much for the feedback!
