Upstairs: The Locked Floor

Follow Deniz’s trail through an old apartment building. Open drawers, connect clues and discover what waits behind the upstairs door.

A locked door. A dead circuit. A familiar voice from upstairs.

Upstairs is an atmospheric mystery and suspense adventure played by tapping your way between rooms. Search for Deniz, inspect cabinets and drawers, use found objects in the right places and connect the clues the building has kept.

FIVE ROOMS, CONNECTED PUZZLES Explore the entrance hall, kitchen, bathroom, bedroom and upstairs room. Find the connections between a tool, a key, a photograph, a code and a fuse. Your journal keeps important evidence, while progressive hints help when you get stuck.

LISTEN TO THE SILENCE Rain, original music and short sound effects accompany your investigation. Hide when danger approaches. Story information also appears as text; hearing the audio is not required to solve the puzzles.

TWO ENDINGS Chapter I — I Heard Your Voice is a self-contained investigation across five rooms with two different endings. The complete main chapter is included in the initial app purchase.

BUILDING ARCHIVE Short document investigations separate from the main story. The Silent Doorbell case is included. An optional, one-time permanent purchase unlocks two extra cases: The Undelivered Parcel and The Midnight Stain. These are document cases, not new rooms or a continuation of the main story. Hints, lives and main-story endings are not sold separately.
