Either the cumulative mindpower of the Backloggd intelligentsia is too weak to crack a simple four-digit combination lock, or this is a shitty failed attempt at an ARG. Considering the only people who claim to have beaten it apparently did so in eighteen minutes or less (an impossibility with how illegible the text is), or deduced the solution with the help of a 'friend' (that player being the dev's brother, their friend being the dev), the latter is more likely. As the game files do not contain content beyond this lock, we the undersigned parties declare this game to be a big piece of shit.

Postscript: drigo figured it out three beers deep at random.
