The investigation was really nice. I just had to wait for the walkthrough because I got stuck at the last password stage. I couldn't find it even if I tried randomly. I'd just found "Hated". Not my proudest moment.
From a story point of view, spending time with "Eight" is very enjoyable for me and Ikuro is becoming more and more endearing. It's quite funny how Graham doesn't manage to spend any time with Dan.
