This game is awesome. My bud showed it to me last month, and man, it's crazy cool.
Pretty much you just try to constantly get to the next level by following the hints on each page. The hints are scattered and are hard to find though, and for most of them you have to look in the source code of each page (it's part of the game, however (it's not cheating)).
Try it out! The furthest I've ever gotten was level 43. There are however, about 67 (that's what the creator told me)
Also it's got a neat atmosphere and story
oooooooooo oooooooooo
