About DC Run
Have you studied electronics or electrical? If you have, you might have heard about the fundamental circuit elements, ie. capacitor, resistor and inductor. In this game you get to play a game and also learn the fundamentals of circuits. In this game, you are DC voltage.
When DC voltage passes through a resistor, it looses it's voltage at the other side of the resistor. When it hits a capacitor, it is blocked completely and when it hits an inductor, nothing happens. In this game, the hero is DC voltage and hence looses 1 of his 3 lives when he hits a resistor, looses all 3 lives when he hits a capacitor and does not loose any life, when he hits an inductor.
