This is a nice puzzle game that reminds me of the circuit board mechanic in Insomiac Spiderman PS4 when he's fixing the robots. Super original and fun. To improve I would make it more clear where the pipes could go with outlines and other things. Also a tween could smoothly transition the pipe from one degree to another. Still good job. If you have time you can check out my game at https://itch.io/jam/gdevelop-game-jam-4/rate/2213787 and give a rating and some feedback.
