I also thought this was really cool!
Made a video that includes my note-taking process (did not do a great job xD):
This is cut down from 1h27m of my 2nd playthrough.
- Sometimes the game lags, for example when making connections between pins, it freezes and then deltas to last mouse movement. got really bad in explore mode.
- I didn't notice anything different in explore mode compared to the final state I left things in. Does that mean I got all docs?
- Totally could have multiple endings, based on what direction the research takes :D (hey, maybe there is and nobody found it yet).
