This is super-fun — it had me hooked instantly when I read the story and the puzzles were fun right away.
The only stumbling point was that I could not try the tones before having to crack the firewall, so the first clicks were random until I found what sound corresponded to which button. The rhythm was sometimes hard to get right, but I guess that’s the point (and I managed after a few tries).
A small tutorial where I click on each tone at least once could help here.
But overall really cool and it left me with a big smile. Thank you for sharing!
