About the Game

約定之日 is a story-driven Card game set in a world choked by a glittering, deadly mist and the creatures it breeds. You step in as the Inspector, guarding humanity’s last fortress and rallying powerful Witches—alchemical beings with awe-inspiring abilities—to push the threat back. Expect tight, tactical battles, a somber yet hopeful tale, and the kind of choices that reward clever play over brute force.

Game Features

  • Strategic Card Combat: Build and tweak a deck that fits your style, then outthink brutal foes with well-timed combos, counters, and control tools.
  • Witches at Your Side: Recruit distinctive Witches, each with their own specialties, and create lineups that spark satisfying team synergies.
  • The Tide Returns: Face the renewed surge of the Crystalline Tide and the relentless Scourge Beasts through missions that escalate in challenge and intensity.
  • Plan from the Front: Operate from a hard-pressed stronghold, organize squads, and pick your battles carefully to keep the line from breaking.
  • Skill Over Luck: Read enemy patterns, manage resources, and sequence your cards to turn close calls into clutch victories.
  • Atmospheric Worldbuilding: Uncover a dark fantasy storyline about sacrifice, alchemy, and fragile peace, told through character moments and tense encounters.
  • Smooth on PC with BlueScreens: Prefer a larger view and precise controls? Playing on BlueStacks keeps your hand of cards clear and your inputs snappy without the usual mobile limits.
