An odd sort of an online game…
Quite challenging. Many solutions require Googling, and you need a bit of a sideways approach – read the page source code for clues, peer at the images with your screen brightness up and down, modify URLs to move on, that sort of thing.
We got stuck at level ten. Found the sound file, but now we need some thing to speed it up and maybe turn it backwards 😉
Enjoy. Or possibly become hugely frustrated.
