The official version is available on Steam for a small fee, which includes Steam Achievements and Cloud Save support.

You play as Qiu Xiaoqi, a girl who wakes up in a mysterious, trap-filled room with no memory of how she got there. Alongside a strange white-haired youth, you must solve puzzles to uncover the truth behind her condition.

It emphasizes a psychological horror vibe through immersive sound design and "heart-pounding" storytelling rather than relying on jump-scare graphics.
