TokiToki

TokiToki is a team-built iOS gacha RPG where players collect Tokis, customize their stats and abilities, equip them, and assemble a team for turn-based battles.

Core contributions

• Designed a reward-based lottery system for distributing collectible characters
• Built an event bus to coordinate audio, visual feedback, and battle events without tightly coupling game components
• Worked with an entity-component-system architecture, rule-based monster AI, status effects, and persistent player data
• Applied clear separation of concerns across battle logic, UI, and data storage

What I learned

Building a game as a team made the value of event-driven architecture tangible: mechanics remain easier to extend when systems communicate through explicit events instead of direct dependencies.
