The game seriously needs a tutorial; it is completely obscure for someone who doesn't know much about circuits. Unfortunately I couldn't complete the first puzzle.
Other than that, the controls and visuals are super impressive! Well done!
Understandable, there's never enough time to do everything. I watched the video and I think I understand a little bit more now. You could say your game is also instructive :D I may try it again later to see how the story ends.
