Only had time for the first level so far, but the presentation is really tidy: the level select strip with the little robot hopping between nodes, and the separate TARGET panel showing the shape you need to build, make the goal clear without any text. I like that the boxes carry their connector stubs, so you can read which side has to meet which at a glance. The screenshots of the later sectors with the coloured copy zones look properly brain-bending. Small thought: on the very first level, a one-line hint that the connectors must touch might help people who skip the target panel.
