I clicked the password box to try and type in a guess, and then what i assumed was a glitch (the background going grey) turned out to be the key to my success. But after I figured that out it was pretty easy. Maybe put a more cryptic hint in the bottle.

Certainly a strange game.  I'm also of the opinion that it could use some more levels to really be particularly interesting, but as a premise, it is certainly a viable game.  Perhaps with more of a hacking element, or clues instead of outright answers, for more of a mystery feel, then perhaps the game would be quite enjoyable.

The theme is quite awesome but the game per-se is really short! I expected a couple more of levels of security :p But the main level is quite curious! Good job!
