《Phantacall Realm》 is a unique title that layers Memory Match (Mental Agility) as its surface mechanic over a deep core of RPG progression, exploration, and deck-building, wrapped in a dungeon-diving roguelike loop.

You will descend into the Realm of Echoes, where layers of mist conceal every choice. Flip cards and match pairs to explore—but until the card turns, no one knows whether you’ll face a sacred goddess, a vicious monster, or a thorny trap.

Within each special portal, you must search for treasure chests and materials, and know when to retreat to secure your gains.

Every dive is a rhythm of tension and strategy.

A Guild System tracks your rank, which rises with your Guild Level. As your character grows and your deck takes shape, new cards and portals unlock. You also have your own personal space—a place to prepare gear, configure skills, select relics, and rest before your next descent.

Memory is not everything. Memory sets your ceiling, strategy guarantees your floor.

You can enjoy the pure Mental Agility experience—an excellent memory will carry you smoothly through battle. But even if your recall is only average, clever decisions and skill synergy will see you through. Skills and relics can also compensate for memory limitations: skills offer powerful active effects that consume mana, while relics provide potent passive abilities. Use them wisely.

Every run begins with cards drawn randomly from your existing deck, ensuring that no two descents feel the same.

Resources gathered during exploration go into a limited backpack—you cannot carry everything. Some will be lost upon death, so knowing when to withdraw is just as important as knowing when to push forward.

Spirit serves as your action resource. Each card flip consumes Spirit, so you must carefully manage your pace.

In the depths of the Echoes, this is no leisurely journey. Over time, a “Spirit Storm” will trigger—a forced reshuffle that upends the current layout of cards.

At the start, you can choose from multiple preset characters, each with distinct starting attributes and growth tendencies. Whether you favor the survivability of the Warrior, the tactical flexibility of the Mage, the well-rounded strength of the Hero, or the exploration-focused Arcanist, your choice will shape your combat style throughout the adventure.
