@bss it's so hard to know what to focus on early on! there are loads of things that look like they could be relevant, but if you note everything it's going to be overwhelming. my approach was to take note of a few things if I felt they'd come up, and leave other things that could just be background for later. main focus was to get to room 46 and taking notes/screenshots of things that seemed to provide guidance towards that.
once things unraveled more, my notes expanded a lot because at that point I knew what to look for and how to interpret it, otherwise it's just noise
