After a late study session at school, you find yourself wandering through a familiar alley—until suddenly, it twists into an endless maze for reasons you can't explain.

Observe the alley carefully and distinguish between Gwihun—supernatural phenomena impossible in reality—and Heoggaebi—eerie but still plausible occurrences.

Uncover the hidden secrets of the alley, survive the ghost that stalks you, and escape before you’re trapped forever.

🔹 A Bracelet That Reacts to Ghostly Traces

Use the glow of a mysterious bracelet—gifted to you long ago by a shaman grandmother—to detect traces left behind by spirits.

🔹 Gwihun and Heoggaebi

Throughout the alley, supernatural Gwihun events blend with Heoggaebi, strange illusions that could happen in real life.

 Take photos of suspicious phenomena and determine whether they are Gwihun or Heoggaebi.

🔹 Story

Successfully identifying certain Gwihun grants you keys.

Use these keys to open the Chest of Truth , uncovering the hidden secrets of the ghost.

🔹 The Ghost's Pursuit

The ghost is always hunting you.

If you sense its presence—strange noises, a chill in the air, or distorted sounds—it means the ghost is getting close.
Run before it catches you.

🔹 Three Lives

The more clues you gather, the more relentless the ghost becomes.

You have only three lives.
Lose them all, and you'll be trapped in this hallucination forever.
