I've made it to the floating(?) part of the game where there are these flowers that open and close. I had to resort to Bert's walkthrough and followed everything to the tee, including locating the book, because nothing I did affected them.
I clicked on the flower on the ground near the start of this area; it opened. Then I clicked twice on the vine/bulb thing above it twice; the flower below closed after the first click, then opened after the second click. No change in color. I tried rapid clicking - still no change. Tried it with the flower off to the right; same thing.
What have I missed? I've gone back to a previous save; no luck.
