Interesting idea. I liked the idea. Some small tweaks that could help are change the cursor or highlight the wire if it's one that I can rotate. Also, it seems like direction of the wire matters, but it was hard to tell which direction was the correct one since the wire just has two ends, not arrows pointing which side is the + and which is the - (or whatever it's called, I'm not an electrician, haha).
Overall, good job for a jam game!
