I really enjoyed this!
The mood is a bit grim and tense, but it's well-supported by the setup and works well with the themes. Once you get a hang of the gameplay, defensive play is relatively safe but also slow, so there's a bit of out-of-game willpower involved in whether you take risks for a faster victory.
I enjoyed seeing the unique dialogs for each played card. If this game saw further development, a history / dialog log would be a nice polishy feature-add, but isn't necessary.
Overall, I enjoyed winning and losing both. Thank you for publishing!
