Like others said the beginning is difficult but once you get it, it's easy. This is really great, it's pretty polished, I like the music icon its a nice touch. I would really like to see this turned into a game, what you have is great but after a few trys it is the same, find the 2 pins you need to connect, if there was way to make it where you need to remember 3 or 4 it would really increase the fun. Great Job! I would have never thought of this
