Just found this, seems to be node programming for games. I’ve never seen such dense nodes, and I like the interaction where you “collect” your nodes in a temporary areas before connecting them in the main flow. This was possibly necessary because it’s on mobile platforms:

So cute and clicky. Fancade is yet another thing I would love to try out.

I found it hard to follow, is it because I am new to it or the way one does it or it is hard?

To me it looks like regular programming, but with nodes and wires. From watching about half the video, I had very little sense of the runtime behavior, and I didn't get a sense that the Fancade provides much introspection. But I also haven't looked very much into Fancade either.
