I've played through quite a bit of it and seen all of the cutscenes. Still working my way through the audio logs between their diary entries, tho. It's quite a game to get through, so I've had to take breaks when playing by myself for too long.

The site has a simplified version that u can use to take notes of which nodes u have seen while playing as well. This really comes in handy due to the massive number of memories there are to go through and it's quite easy to lose ur place in-between play sessions.
Another good resource that made the game a bit easier for me to understand before fully diving into it was this YouTube video by Hazel:

Hope this helps, and let's all love Lain
