Treasure of Y is an adventure-themed turn-based RPG where players explore ruins and unknown areas, progressing the story through movement, collection, and puzzle-solving, and engaging in strategic turn-based combat when encountering enemies. Players must choose skills, plan their action order, and allocate resources wisely to defeat different types of enemies, while also building their own combat style through equipment and relics. The game's main appeal lies in the new discoveries brought by exploration, the strategic depth of turn-based combat, and the mysterious world background that gradually unfolds as players collect treasure fragments.
