Puzzle Paths

Funny game. The controls are a bit annoying with a touchpad. Dragging the line over the map button closes the current puzzle. A button to replay the level after completing it to get it solved for three stars would be nice.

Uhh I started to get confused at the part where there's those dots. What do they do, allow criss-crossing? A tutorial or window explaining this method would make the game more clearer.
