Nice, but there should be more clues.
I liked the game a lot, but the only problem I had was that (as far as I could tell) there were no clues as to how the wires should be connected. I did most of it by myself, but I had to go to the walkthrough to find out how I was supposed to connect the wires.
I think that you shouldn't have to guess in these games, because then you're not figuring out how to do something, you're just clicking things until it works.
