There should be an "Unflappable RPG Protag" reward for Lera. Jokes aside she seemed to handle the situation pretty believably. In general I liked how grounded the atmosphere was despite the surreal environment. Nika is quite likeable, a perfect representative for the creature to dole out their message. Hell, if I was in this situation I would have let her convince me of the hopelessness of the situation in a heartbeat.
I love/hate to eat up existential works like this, they really stick in my head. I am still struggling to find the words to describe how it makes me feel even now. Great work.
