@Vainilas I too have experienced this. More frustratingly though, is that every time I load the page, my progress is RESET. I wonder if someone has a saved profile at level 30?
krezjziakBH - thank you, thank you, thank you! your Level 16 link worked.
So people don't need to go too far to find this, here: http://www.kongregate.com/games/ArmorGames/this-is-the-only-level-3?acomplete=this+is+the+only+level
It's great for people w/ a bitchy Firefox
