About This Game

You arrive at an apartment building on the south side of the city to visit a friend you have not seen in years.

The door to Unit 305 is unlocked, but no one is home. A note has been left on the dining table. Your phone has no signal, and the hallway you just crossed no longer feels familiar.

When you try to leave, the building changes.

Explore a Shifting Apartment Building

With each new loop, its rooms, exits, and connections are rearranged. Residential units, management offices, underground facilities, and spaces that should not exist are joined together inside the same building.

Before opening a door, you can never be certain whether it leads to a familiar corridor—or to a room that was never there before.

Investigate What Was Left Behind

Examine personal belongings, documents, local reports, maintenance records, and traces of everyday life. Piece these scattered details together into Knowledge that persists across loops.

Clues can support and transform one another. An anomaly that once seemed meaningless may gain a new explanation later, while evidence you have already uncovered can improve your chances during investigations and attribute checks.

There are no objective markers pointing you toward the answer. You must decide which information to trust—and where to investigate next.

Carry Understanding Through Every Loop

When your Steps run out, or an encounter leaves you unable to continue, you return to the beginning.

Most physical items cannot be carried back. Knowledge can.

Major discoveries are converted into Insight, which can be used to strengthen your attributes and expand your ability to explore. Each loop may take something from you, but it should also bring you closer to an exit.

Decide How Much Risk to Take

Movement, investigation, and special actions consume a limited pool of Steps. Some anomalies may also damage your Health or Sanity.

Strength, Agility, Perception, and Sanity determine how the protagonist handles different situations. Equipment, clues, and evidence can affect the outcome of attribute checks—leading to new discoveries or bringing the current loop to an early end.

Your chances are shown before you commit.

Whether to proceed is up to you.

A Message from the Management Office

There is a visitor registration terminal inside the management office.

The first time it lights up, a message is already waiting:

If anyone can see this message, stay calm.

Who left it? Are they trapped somewhere inside the same building? If a message can get through, why has every other form of communication failed?

All you can do is continue investigating, and wait for another reply.

Psychological Horror in Everyday Spaces

A newspaper printed with the wrong date. A room missing from every floor plan. A phone call with no identifiable source. Another corridor appearing for an instant when the lights go out.

The building’s abnormalities emerge gradually from familiar, ordinary spaces.

The real danger may not be what waits behind the next door.

It may be the moment all of this begins to feel normal.
