This jam entry had the highest technical load, so I had little time to think about level design/content. Introducing new nodes that would aggregate data, not just filter it, would indeed make it better. Thanks for playing and for the feedback!
Having tried to build a node+connections UI and data across and such, I know a little bit of the pain (a teensy bit). The UI/UX is certainly very elaborate and looks polished as heck! Hope you can take the ideas and run with em again someday :)
