"Sudeki" is an action role-playing game where players take control of up to four characters, exploring a variety of locations including towns, rural areas and roads, wilderness, and underground temples and mines from a third-person camera perspective. The world is split between the main world Haskilia, the mirror world Akloria, and the Realm of Shadows. During exploration, the party can interact with non-playable characters (NPCs), break containers to find items, interact with local merchants and blacksmith characters, and discover treasure chests. Each character has a dedicated health bar and skill point bar which powers magic and special moves.
