You have found yourself in a space that reminds you of nothing, and everything. A space of rooms, that are both comfortingly familiar, yet strangely unknown. A space of quiet and loneliness. You have found the BACK*SPACE. You aren't sure if you are alone. You aren't sure if you want to leave.

From Steam’s client network, last checked . Builds before 21 Oct 2026, when we started watching, aren't listed. Patch notes are the developer’s update post from an hour before to a day after the build. Not every build gets one. How we count
