This game absolutely rules! I've had a similar idea knocking around in my head for years, and could never work out how to make it into an actual game, but this is such an elegant mechanic - imo the best hacking game I've ever played. Wonderfully tense, while not punishing my frequent mistakes too harshly. The ending left me with a tear in my eye and a grin on my face. I'd love to see this idea developed further, it has so much potential.
