Hm. Now that I am the Node Master, after all these levels, I'm still undecided.
On the one hand, the sci-fi design with the animations, messages and grid looks good, it is easy to use, and the theme is done excellently.
On the other hand, I asked myself whether it is a game at all... it starts as a test of network knowledge until you seen the ghost hints which allows to connect just the nodes by the lines you see. No challenge here, no tension, no fun - at least for me. I think the hints should be optional, and off by default - else it gets too easy.
The puzzle was not contained in a story and I heard no sound at all.
I admit this is not my type of game but it looked interesting. Still is. Very futuristic and clean. Technically nice, and probably great as a minigame in a bigger game. And I liked that I could zoom and rotate the grid.
