Interesting and engaging story. Presenting evidence during battles really does help make the themes cohesive with the gameplay, it isn't just a reskin of roguelite card systems. The backstory tying into the starter deck is a nice touch and the cards you get from it are sensical. I don't feel like the type of response selected in minor events really reflects the type of cards you gain from these encounters, however.
The battles themselves feel a bit too slow, and it's easy to fall into long loops trying to build up ressources while preventing the opponent to do so at the same time. This is especially true when experimenting with decks on first runs.
I tried various combinations and backstories and ended up with a lot of different save files, I haven't been able to delete them so there's a lot of clutter in my menu. That said, Second Layer comes out in a few hours so maybe all of this will be a non issue in the update.
