Story

A group of friends like to explore and investigate abandoned buildings.
One day, they decided to explore an old, weird mansion in their town. While they were investigating the building, they felt something was weird.
That's when they noticed they were disappearing one after another, except for the survivor, who has escaped safely to tell this story.
He could tell us more about what was weird there and the cause of his friend's disappearance, "Juwaira", as he could hear her whispering her name. A blind and strong-hearing old lady, as she can hear everything around her, which was the cause of the "death," probably to his friends since they weren't aware of not triggering her by any sound.

You and your friend's mission is to finish each floor's riddles objective to reach the last floor and purge the spirit!
