Kinda meh.
Certainly not the worst puzzle game, but it does feel disappointing in many regards. The puzzles themselves, actually, weren't as hard as they could've been. Most of them relied simply on some form of decyphering (be it morse, binary or hex), and the ones that remained (actually, the other two) were about simple googling. That leads me to this game being shockingly short. For such a type of a game there could've been a huge potential of diverse puzzles, maybe utilizing coding, or improving on the interesting automated email responses idea, or maybe making something akin of elements inside the OS itself, but alas.
The hex puzzle in particular left me, pardon, puzzled for a short while. The whole dashes and carets thingy, as far as i'm concerned, was just a red herring irrelevant to the puzzle in question. The thing that worked was googling the decyphered gibberish that you got from decyphering a hex message. And i did it by accident. I do get the feel free to use Google line, however, making it mandatory is somewhat reduntant and ruins the whole aesthetic of breaking into one's computer (Why would this Albert guy ever use a reddit bot to hide his password?). Elaborating on the story (at least by some text files, or by other means) would've been cool too, as it feels lackluster in its curent state.
Overall, if you're about to release a paid version of the game, consider improving it substantially, for now, for a good concept, the present game doesn't offer you much. 5/10, 3/5.
