I genuinely enjoyed the puzzles! Despite it being a demo it already shows a high degree of visual polish (love how the lines strech and bounce when the orb flies around). Super promising and extensible idea. I'm looking forward to more puzzles and new puzzle elements.
Also I find it impressive that the puzzle is visually clear and understandable without any written instruction. That speaks for strong visual and puzzle design, really good job!
Little polish idea: the orb could follow the player's cursor with it's gaze (like the shapes do in Is this Seat Taken for instance)
