Nazo Waku Yakata – Oto no Ma ni Ma ni Daiichi Wa – Hikarume

A quiet mansion is filled with strange sounds, and the story follows the player as they explore rooms where mysterious noises hint at hidden secrets. Each area shows clear corridors, doors, and interactive objects that guide the investigation while revealing clues about the mansion’s mysteries. Players move through different rooms, search carefully, and uncover puzzles hidden within the unusual sounds.

Rooms contain puzzles that require careful observation and thinking. Some challenges are simple, like matching shapes or listening for patterns, while others involve timing or arranging objects to follow the sounds correctly. Certain areas include mini-tasks, such as opening locked cabinets or activating switches in the right order, giving points or unlocking new rooms. Visual feedback appears immediately when a puzzle is solved, showing success and guiding the player to the next step. Controls are simple, allowing beginners to explore and interact with objects without confusion.

As the mansion reveals more rooms, new puzzles and challenges appear. Some areas include multiple sound-based clues that must be interpreted together to proceed. Later stages introduce trickier sequences, hidden passages, and puzzles that require careful attention to timing and order.
