this game looks interesting! it reminds me of Alkahistorian volume 3, with all the nodes and things, but with the potential to be more open-ended and theorycrafty.
some suggestions:
• take out the triple lined connections. it doesn't make much sense to have connections that cannot be removed, and without them there would be more potential for experimentation
• you should probably figure out a way to anti-alias the text on the nodes for wide zoom levels, or otherwise remove the text if it gets too small
• having the ability to split or merge same-type nodes (to a reasonable extent) would both reduce node clutter and allow for more complex routing
• when mousing over a node, it'd be useful to highlight nodes that produce, store, or consume the same resources as the highlighted node, just for QoL. additionally, it could highlight which nodes it is currently connected to, with separate colors for sending and receiving
• it'd be good to have a discord server for this, just for the sake of having a hub for update info and suggestions
