The writing in this was wonderfully oppressive.
I loved the vibe of the whole thing, and I saw a few places that the narrative probably diverged. The world wasn't over-explained but gave more than enough to latch onto. The creeping ecological issues, the work in a dangerous pirate situation, the separation between the two characters -- all really worked for me.
The choices didn't seem all that meaningful - putting the letter in the pocket? It felt like an important thing at the time, but ultimately just felt like an interesting roleplay moment.
