Walkthrough
Last checked 2026-11-03
This is a route, not the route. Day 1 the building changes and the wounded neighbor matters. Apartment 32 opens on day 2. The ground floor wants discs that sum to 3. The basement wants the third rent. The roof is the end of that staircase, not the first errand.
Day-by-day checkpoints
Calendar events are checkpoints rather than a requirement to clear one floor per day. Source coverage: 1 independent source, Miraheze Gameplay; checked 3 November 2026. Empty cells mean the referenced table does not supply that field.

One lower-floor route
This is a workable order of progression. Side rooms, companion quests and optional bosses can change the itinerary. Source coverage: 1 independent source, Miraheze Gameplay; checked 3 November 2026. Empty cells mean the referenced table does not supply that field.

A calendar you can check
Day 2 is Joel’s first lucid day and Clint’s appearance in the Floor 3 hall. Day 3 opens apartment 31. Day 4 changes apartment 32 and opens 38, which is Pierre. Day 5 shuts 32 and ends Joel’s recruit, and opens 30. Day 7 is the last day to gift Charan. Day 8 is the earthquake and Charan is gone, which is also the wrapped-painting cutoff. Day 9 reopens 32 as Teeth Hell. Day 15 is the last day. Day 16 is the No Going Back ending if you simply lasted.
The stair I trust is apartment 21 down to Floor 1, the sum-of-3 door onto the ground floor, the basement key, storage into the sewers, and eventually a roof key. I am not numbering every closet. GameFAQs has image maps by Cyrus917 for several floors. Those images are a second source for “a map exists,” not a license for me to redraw them without looking. I link the floor pages instead.
The convenience store is a ground-floor or fungal-side errand depending on the key you hold. The Store Key from the Fungal Lair is the one the key list names. I will not invent a shopping list.
If you are stuck, the usual cause in the search data is the ground-floor sum or a save meter, not a missing cutscene. Read the disc page and the saving page before you restart the week.
