Stuck on the 1st puzzles with the knobs??

Turn all the knobs to follow the flow of the green line (don't forget the little one)

Icescape 2 is the sequel to Icescape and features more escape the room style puzzles along with a shoot-em-up element that some will like and some will hate ;-) and the temperature timer has gone!!
