Addictive puzzle game.
The goal is to connect the two endpoints of the puzzle to form a path. To do this you must re-position the parts by connecting them to one another.
To move the parts around, just click on one piece, then on one of the adjacent parts and they will change position. Each time you add a piece to the path, that new part will light up. To make things more complicated, new light bulbs will appear along the way. You must pass them to light them up and to advance to the next level.
