Fighting with the ghost on the green-torches scene is way too complicated, cannot get past it.
In one of the first updates there will be campfire in the area next to the boss. :) It will be much easier to re-try then!.
At this point My advice is - always take care about torches first. As soon as one of the lights back stop what you are doing and take care about torches again. Let me know when you manage to beat the boss!
