Complete Walkthrough

Follow a staged route through the investigation when gentle hints are no longer enough, with clear spoiler boundaries for each phase.

Spoiler note: this page keeps direct late-game answers separated from early investigation guidance.

Early investigation route

Begin by confirming the machine interface, mapping the first accessible rooms, and listing every person or number the game introduces.

Main deduction progression

When progress stalls, identify whether the blocker is a missing person, a wrong room, or an untested time. Solve the blocker before scanning every possible code.

Endgame and cleanup

After the core case is solved, revisit unresolved rooms, optional memories, achievements, and hidden interactions with full spoiler warnings enabled.
