Exploration Mechanics
The game places you in the nightmarish Sehwa District where you must scavenge resources, trade items at Dokaebi Market, and unlock tools to reach previously inaccessible areas. Exploration is urgent; running while wielding a flashlight makes you an easy target.
Balancing speed with caution is essential, as the AI pursues you relentlessly. Hiding can prevent certain death, while careful navigation opens new zones and advances the story.
- Gather items before venturing deeper to reduce back‑tracking.
- When the AI is near, pause and hide instead of sprinting with the flashlight.

Pursuit and Survival
A relentless psychopath with more vicious AI chases Youngho throughout the mirror dimension. The killer relentlessly pursues Youngho, so evasion and hiding are central to staying alive.
The AI’s behavior forces decisions between confrontation and flight, creating tense moments. Survival hinges on timing, hiding, and judicious use of limited resources.
- Observe the AI’s movement patterns to find safe windows for movement.
- Conserve scarce items for moments when evasion becomes impossible.

Trading and Resources
Dokaebi Market serves as a hub where you can trade items to prepare for critical life‑or‑death situations. Scavenging the district yields resources you can trade, while tools and upgrades unlock previously inaccessible areas.
