There are 5 lanterns. Each has a different amount of effect over the currains. When you start, they are all burning a little. So to get the curtains all the way open, you have to seek out the other lanterns and fill them up too.
As for as for having too much wood.... I tried to balance it some, but withore time I think it could be made better.
Thank you so much for playing it, and for the feedback!
