on level 5 i tried to modify the url, but my quotes are automatically encoded, also tried encoding it using %22.. but didn't work.. I'm using chrome on osx, could it be a browser thing, i managed to get it to work by manually modifying the html using the developer tools :p
Anyway pretty good UI, a few suggestions:
Perhaps you could add a graph of the normal distribution and where you lie on it.
Choosing the location of your workplace is a little confusing at first, it might be more intuitive to make it similar to the Facebook checkin sections, show a list of places nearby.
Just curious if you are making any ad revenue yet? :P
