Gameplay
Players are able to create their own unique characters in the same style and fashion originally present in Mobile and Kingdom Hearts Re:coded's Avatar Menu. Battles consist of a strategic card-battling mechanic with a large emphasis on collecting cards and items. Cards can also be synthesised to level and evolve stronger cards and materials can be synthesized to strengthen the Keyblade's abilities. All controls, including moving around the field and battling, use the mouse. While the game can be experienced in single-player, cooperative multi-player is an emphasized element as cooperative gameplay is required to defeat raid bosses, which appear several times throughout the day. Additionally, players go into five teams in which players defeat enemies together to collect light known as "Lux". At the end of each week, the total amount of Lux for each team is calculated and the team that gathered the most, take part in a mission where players can obtain special rewards.
