I accrued a lot of in-game stress early on trying to guess the password from previous user commands. After noticing the 1:1 correspondence between password length and log output, things started coming together from there, though I did putz around with strictly-alphabetical passwords before realizing I needed to switch to numeric. From there, the general idea of the game becomes clear and starts to unfold more rapidly. I made it to the final level, but I ultimately ran out of time before draining any accounts. The final mission then restarted (yay!) but I died of a heart attack right after.
My overall impression is that I really needed the out-of-game hints on the game page in order to progress. The flow of the game would be helped a lot by working these guidelines into the commands and/or console hints. The final sequence can probably also last a fair amount longer without being too easy.
Otherwise, the exploration of various barriers and vulnerabilities did do a lot to build the immersion of being a hacker on the outside trying to hunt for some kind of ingress! I also liked the choice of music. It felt very data-spacey.
