Thank you for the game!
I am not a very good puzzle player, so I was unable to finish it. I've deciphered the name of the company CEO and got to his page, but failed to understand where to apply the cipher from it. This was too dramatic jump in conceptual difficulty for me. But I can’t say with absolute confidence that this was the game's fault, since solution might have been just around the corner and I have missed it.
The idea of presenting crucial game info throug separate files is really interesting! I found myself organizing screen space of my laptop into a make-believe research desk, as I divided it into sections to see both game and notes windows at the same time. This provided game with a sort of 'found footage' quality. The dicision to include in-game player character and narrate exposition through the cutscene worked somewhat against this effect, though: on the one hand, I was myself figuring out the clues that were physically present on my laptop, and on the other game assumed that I had to project myself onto the image of some hard-boiled noire P.I. on the screen, as he rummaged through the clues in his office. I felt a dissonance between these to narrative poles and think that game would benefit greately if it would consistently adhere to only one of them. What if, say, the executable file of the game was framed as a kind of database you have to navigate through, and notes - as email that you recieve from the unknown source? This would shift focus further from the game as a self-contained digital object, and emphasise that player herself is an in-game character.
In any way, thanks again and keep up the good job!
