Connecting the nodes is pretty satisfying! For some reason, I kept messing up the controls and I got stuck on the level right after the tutorial.
I am sorry to hear that, what was confusing about the controls? Was it selection, connecting nodes, moving nodes or bringing up the node menu?
I am glad the feel of connecting was good. I put a lot of focus in getting node control right, but I know there is much to improve.
I kept left clicking on the green node to bring up the connection menu. And then when I was moving a node, I kept wanting to left click to confirm the location instead of right click
