Thank you very much! I did indeed go pretty much random with the pictures. I had a massive collage of usable images at the start of the week, but of course I soon had to scale it down quite a bit, and just pick the ones I'd be able to stitch together without too much editing.
And yes, you need to visit the girl in the book to be able to progress in the forest on the left side, but it's definitely a bit tricky. In case you want to try again, you can make your way across the dancers and the shoreline to get back through the desert on a lower level. It may involve a few more finicky jumps though :)
Thanks again for your kind words!
