What is Stabjack?

Stabjack is a story-driven deckbuilding game in which Jack fights demons with the knife that killed his wife, now speaking in her voice. You draw cards to strengthen attacks, defense, or preparation, aiming for 21 without going over and forfeiting your action. Investigations involve examining wounds and environmental damage to identify culprits.
