Room Numbers

The main feed is down. The annex is running on a backup generator that carries two circuits at a time, and every door in the building wants a four-digit code.

Those digits are printed inside the rooms, on screens and signs that only read out when their room has power. So the puzzle is never "find the code". It is "decide what to leave in the dark": pull power off a corridor you already crossed, push it into the room you still need, and walk back through the dark you just made.

Doors seal behind you. The route only runs forward.

Controls

WASD move / mouse look / E interact / 0-9 type on a keypad / Backspace erase / Enter submit / Esc cancel and pause / R restart

About

Made solo in Unity 6 (URP) for USC CTIN 389: design, gameplay code, level layout, models, lighting, UI and audio. A run takes about three minutes and the ending screen reports your time.

macOS note

The macOS build is signed but not notarized by Apple. The first time you run it, macOS may say it cannot verify the developer: right-click RoomNumbers.app, choose Open, then confirm in the dialog.
