I was impressive by the subtlety with which the wires can cross or not.
Very realistic physics where you are trying to thread the needle.
I was expected much larger and harder to handle collision volumes, but this is sleek.
Two things I would suggest changing:
1) More tutorial info (or more obvious if I missed it) explaining the rules of the game, and the meaning of the colour of the wire. I was stuck on the 2nd room (I think) with 3 holes and 1 cable - couldn't figure out how to "plug all the holes", didn't realise cables weren't allowed to touch the ground, and didn't realise what the red was trying to tell me until later. I thought the red was just a stylistic colouring. I brute forced the room very quickly; and I didn't see the red moving until a couple rooms later.
2) Music with a longer loop and/or no high pitch noises? I found the sound of what I thought was a record scratch or whistle to be immersion breaking, and I also think it was the loop point. This can be a problem for any genre; but puzzle games in particular need to have music that doesn't distract the player while they are thinking.
Overall, you've done a terrifyingly good job.
I would not be surprised if you said that you took the full 2 weeks to develop this.
