【Game Features】
*Featured chapters · Supernatural puzzles of different styles*
Horcrux: Go deep into Mutuso Town, collect soul containers and prevent the crisis of world destruction.
Immortality: Decipher Tuya's time-space paradox letter, uncover the truth behind the Ewutansi tribe, and find a way to save Tuya.
Alien: Hunt down the alienated scientist Selon, explore the abandoned laboratory, and face the deadly threat of the mysterious alien beast.
Tracking: Board the Golden Polaris train, outsmart the black market forces in a limited-time crisis, and recover high-risk energy.

*Brain-burning puzzle·Cross-chapter clues*
Interlocking Mechanism Design: Roman numeral code, spell box, firefly pattern array... Puzzles requires combining multiple scene clues: I never expected that the pattern that appeared in the first chapter would be the key to the formation in the final chapter!
Hardcore Interactive Logic: items need to be clicked accurately, scene clues cannot be carried across levels, but information can be reused, which tests observation and memory.

*Exquisite Art: Collision of Primitiveness and Technology*
Spooky fireplaces, tribal temples, steampunk laboratories...Each unique scene presents a fantasy art style.

*Core Gameplay: First-person Investigation*
Collect Everywhere: search under the bed, fireplace, password cabinet, collect key props such as fire tongs, kerosene lamps, mysterious letters, etc.
Combination Cracking: use wooden boats to start fires, use crowbars to open locks, and use Roman numerals to unlock cabinets.
Logical Thinking: The number of patterns is related to the password, and the password hidden in white paper under specific lights.

The collection includes four complete plots:
"Horcrux", "Immortality", "Alien", and "Tracking", which are large and satisfying, allowing players to immerse themselves in puzzle solving.
