I really liked the game! One thing that immediately came to my eye was the huge tutorial wall. Try to avoid this since it will stop some people from playing your game.
I really like the concept you came up with since it is something everyone knows but it is not often presented in games. It is very unique. Another suggestion would be to also show people which cable is which since it could be that some people don't know cable types :)
Other than that great game! Love the untangling mechanic.
