I love a strange sci-fi world, and this certainly delivers. As you've noted in the credits, the overall tone certainly isn't light, but that's fair. It's upfront about what kind of game it is. There's nothing wrong with a darker story every now and then, and the writing here has a very strong voice.
The combat system is quite impressive - this is a real achievement for a jam game. It's asymmetrical but balanced, and everything makes sense and works well together. I did find myself wishing for more control over the cards in my hand, but once I understood how the movement/willpower system works, I was able to plan my moves and win the battle on my second try. (If you did want to keep poking at this some more, it could be one of these indie deck-builder RPGs.)
Honestly, the sheer amount of detail in this is impressive. From the animations and sound effects to the in-combat dialogue to the gosh-darn tooltips. It's all dripping with style and atmosphere.
