Beautiful ASCII art style, loved the look of the game. I made it to Sector 16 and then the exit seemed to be behind a wall with no entrance to it. Admittedly, I quickly focused on the game instead of the text, so I missed out on a good bit of it. I also love the idea of the paths you've walked collapsing behind you, very poetic.
I sadly didn't understand what integrity, output and energy meant and did, and also what the "&" and "z" enemies/obstacles did. They seemed to disappear once I ran into them with no further consequences.
I'd also loved some 8-bit chiptune in the background, or something of the likes, to not play the game in full silence (the silence could of course be a stylistic choice, so I may be in the wrong here).
All in all a cool little and beautiful game!
