Actual interface captured from the September 18, 2026 test build. A saved game state was prepared, then the device was opened for interface review. This is not a full-playthrough recording or an Episode Two image.
The role of the puzzle
The final wiring board is not an isolated minigame. It routes power to the front shutter. The player collects red and blue wires in the records room and lobby, then repairs the broken circuit behind the front desk. Completion must visibly raise the steel gate in the main scene and open the next action.
The early version used small colored points that blended into the background on mobile. Inventory entries were text-only, making the two wires difficult to remember. We added dedicated item images and distinguished the wires by terminal shape and position as well as color.
One input, one response
To connect wiring, select a cable and then select a socket. No dragging or long press is required. Keyboard users can focus a target and press Enter or Space. Generic tap feedback and puzzle-specific playback paths are separated to avoid playing both for one input.
Connection feedback is separate from a correct-answer verdict. The short plug sound confirms the input, not the solution. Use MIX to test the mixed-color circuit. A misplaced cable can be disconnected or moved to another socket before checking again.
State change and sound
The shutter sound no longer plays when a wire is selected. It begins only when every connection is complete and the steel gate starts moving in the main image. The success cue is short and the motor remains low so the two layers do not compete. Investigating the locked gate uses a solid metal impact rather than a doorknob sound.
The basement failure route starts its gas release immediately by trimming silence from the source file. Success and death involve the same equipment but use clearly different sound and visual changes, preventing the player from misreading the outcome.
Reading the board in three stages
The board separates red, yellow, and blue inputs, mixed-color outputs, and a final reconstruction stage. A connection made earlier becomes material for the next stage, so the task is not simply matching identical colors. Connection state is shown for each stage, while full power restoration waits for the final circuit check.
Review must distinguish three events: selecting a wire, connecting it to a target socket, and completing the circuit. A selection sound alone must not announce success; the connection display and the room change after power restoration complete the feedback.
