There's a lot of complexity, but the concept is pretty interesting. I like how bold and radical it is. But it also makes the game a bit too unforgivable. I like the idea of planning carefully, but less being out of option when facing a threat and knowing I'm facing a certain doom. Perhaps there lack a "last resort panic" mechanic to be able to reacts to a threat (for a great cost or as a risky maneuver). Also the size of the map makes the guard moves pretty unpredictable, making it hard to determine when I'll need to hide or escape.
But it was still fun to try beating it! The UI is clean and fast to use once you understand it. And each card explains itself very well (except maybe the diversion)! Great work also on the art and music, the game looks nice and has good feedback.
