What's interesting is that I'm totally not target audience for this type of game, but I'm surprised that I've been really enjoying myself during the entire playthrough !
You did an amazing job regarding the narrative/ambiant quality. It reminded me of the stress feeling you can feel playing frostpunk, this feeling of "it will be harder and harder". For me the game balance was really ok, I struggled enough without being too much in pain, which allowed me to be kept entertained so on that side too that's a really good point.
A smart decision you made (which might not have been quite easy to do regarding the time you must have invested writing everything) was to summarize what every decision would imply. It allows the player to read without feeling the "need" to read, afraid of losing a piece of information. That made me really more immersed than I though and might even have reconciled me with this type of experience.
