Choose the correct path and collect the orbs along the way, as you'll need them to light up the circuit at the end. Don't forget to collect the coils on your way. Also don't miss the orbs or you won't be able to see anything. So, collect as many orbs and reach the end before everything turns dark, and try to light up all the coils at the end of the path. Good luck!
