Very cool! I'm stuck on level 7 because it seems that the script isn't editable anywhere. Related note, the color scheme for highlighting editable lines might want to change, because "black on dark maroone" doesn't exactly jump out.
Love that you're auto-gisting solutions. That was clever - I presume you are browsing through searching for the common description tag? I also like the API popup, although I didn't see it until I got stuck on the (uneditable) level 7. I verified this because $('.editableLines') == [] in console! Perhaps this is a very fancy meta-game that you can only win with a pull request? :)
