Finally got her in my last couple notes after 5 turned up blanks. I had to sweat my ass off in immersive theatre. Going into the last difficulty I have no business being in (I barely beat the previous difficulty with 4 seconds to spare) and thankfully Lynn is strong enough to carry my ass to 10 stars.
The only thing I wanted was a copy of Psyche. I would have been very depressed if I didn't get it in that final batch of secret notes because I legit don't think I'd be able to get 10 more stars for another shot.
