Excellent concept ! This is a really great way to teach kids the basics of circuits. And the fact that it is also a maze type puzzle game makes the game appealing to even those who don't like circuits. Looking forward for more levels and elements.
My only issue is the lack of "go back a step" feature, or in other words, a checkpoint feature. Having to restart the whole circuit every time you make a tiny mistake can get frustrating, especially in the levels where the circuit is big and complex. Besides that, it is a fantastic game.
