Okay in Outer Wilds I have now figured out
Quantum Entanglement. That's really cool but I'm not yet sure where else to apply it, since you need
complete darkness for it to work so not that much outside of Ember Twin's cave is even suitable for it. Maybe something in Brittle Rock, I dunno. Speaking of, I also got inside that observation dome on the south pole and that diorama showing the Eye of the Universe (assuming that's what that explosiony-looking symbol represents) teleporting around the distant reaches of the system was super cool.
Also I really enjoy the peace that comes along with sitting in a place after exploring it thoroughly, knowing I don't really have time to do anything else, and waiting for my death while the tunes just linger around me. I got onto the
Sun Station and after getting through all the information there, saw the thing that said I had about 45 seconds to live, so I just turned to face the Sun at watched the end come in silence. It was very serene.
So thanks again
Jubbe and
Tharp for reminding me to get back into this. I'm head over heels and will be getting back in once I'm home this evening, as much as I don't want this to be over.
