Well, I've made some progress, but no codes so far. Stuck in a maze that I didn't feel a need to graph at first but it just kept going on and after about 10 minutes I'm pretty hopelessly lost. Did manage to break through a wall momentarily but I think that was a bug not a feature.
Couple things that threw me a bit:
several .txt files I couldn't figure out how to display, but obv opened one with the password hint. Not sure if the others are meant to be opened for progress or corrupt for ambience.
once logged in to dads pc i couldn't figure out how to disconnect and get back to paul's without relaunching the game
Anyway, gotta go do breakfast and family things. bbl.
Fun and challenging so far!
