About the Game

The girl wakes up in a research facility, where the same 32nd floor loops….

Control the test subject, “Nonuple Nine” to explore the building in side-view perspective.

Click on points of interest, collect information and solve the mystery of this world.

You can find manga, online meeting logs on computers, and business documentary programs on TVs, in different formats.

Containing more than 1700 graphic files, events have their own visual styles.

Overwhelming density of the visual presentations will make you want to see more.

Everything you see is there to progress the plot to the climax.

With the latest scientific findings and the supervision from experts, this game will change how you “perceive the world”.

The developer of this game was the scenario writer for several titles in the “Ace Attorney” series.

The BGM for this game was created by the composer of “5 Centimeters per Second”.

While being a small-scaled indie development, this roughly 30 hours game took more than a decade to create.

Q1: Is this a Horror game?

While the game contains dead bodies and blood, but I do not intend the game to be scary, and I aim to provide surprise in discovering the truth and insights, which also come with suspense and curiosity. There will be no loud “jumpscares”.

Q2: Is this an Escape Rooms game?

Escaping from the facility is your goal, but this is not a traditional “Escape Room game”.

There are little action or puzzle elements included, and the game focuses on exploration and story. You won’t need to have good skills or reflexes to play.

Q3: Are these trailers and screenshots on the storepage part of cutscenes?

There are very few “cutscenes” where you can only watch and cannot interact. Most of the events happen as you progress on your own pace.
