Use the white dot to connect the battery to the light so the pulse can travel along it. Click to begin and end drawing, not click when drawing. Click the "?" for help about what the buttons do if you have a question. I will make more levels if I get 20 views. ***HIGHLY RECOMMENDED: Use turbo mode to speed up the pulse. Shift-click the start button for turbo mode.
I programmed it all myself and used scratch sounds. I made all of the vector graphics.
