I think the mechanic is really cool & I just wanted to provide some thoughts.
First off, I love how its written in a conversational tone. I can see the vibe you're going for and it totally works. Its great how you included a brief summary of how the mechanics play out - but iI feel the DIVE IN section could benefit from having an infographic, or an example of how it plays in action (I had to re-read a few times before it sunk in). I love how you've included tools to scale the mechanic difficulty, and flavourful in universe items to make it easier. The main issue I noticed is as the complexity increases I could see it taking a really long time to perform a hack. If the defender rolls a 50 and the hacker rolls a 20. They would need to node jump 10 times, to match the defender's result (and that is just 1 layer). Maybe have the Node Jump range increase with the complexity as well?
Let me know if I overlooked something, because I feel this process could take a while and be a lot of dice rolling.
Overall it's a fun read, and I would be interested seeing it in action :)
