Once you go down on the second elevator, the path is pretty straight forward (i.e. you don't have to choose which way to go) but you will probably find that there are lots of places where it looks like you can get off. Just do the usual 'click everywhere' thing until you get to a point where you can't go any further.
At what point are you stuck?
There is a large curled up leaf in front of me
I can see what looks like a trap but cant get to it
What do I do with that trap thingy?
