Nice idea!
My game is actually the opposite of yours: you have to set the block while your game is set the wires.
I love the colors and the animation!
I would advise to make it a bit more progressive: it took me some time to understand how to open gate (but that's ok) But I really feel stuck to finish the last level. I was not clear that the first sockets need to be plugged together to end the level.
Still, congratulation! Amazing work regarding the time to create it
