The bad, secret and true endings, office key, Ollie’s friends, chest code 4520 and hospital puzzles explained using the developer’s guide.
The three endings hinge on information gathered before the roof. Discover a clue in Dr. Tetra’s office, or complete Ollie’s friends quest and talk to Ioro in the shop while alone. With that information, talking to Mary on the roof gives the true ending; obeying Dr. Tetra gives the secret ending. Following the doctor without the clue gives the default bad ending. The office key is optional if you use Ioro. Spoilers follow.

Route through chapters 1–5
Chapter 1: Stand above the fifth-floor spills to clean them. Take 5 MONEY from a doctor’s coat and buy TEA. In room 304 color the cat’s eyes blue then red; open the box in rainbow order. Visit 605 before 604. Type MARSHMALLOWS for Gus’s burger and bring the blocks and cat toy back to 604.
Chapter 2: Restaurant tip→rose at the flower shop→picnic vase→return the water pitcher to the restaurant→buy the bouquet with the larger tip. Break Hyllindrix’s three-round card-game loop by seating Mary behind him.
Chapter 3: Find the hidden passage in the basement spare room and open the chest with 4520. Releasing the laundry mouse gives Mary +1; killing it gives Dr. Tetra +1. Solve the ten-switch panel and cross the maze.
Chapter 4: Collect Gigi’s key at the sixth-floor vending machine and a screwdriver from the fifth-floor janitor closet. X-ray the skeleton’s detached hands, follow the computer’s directions, cross the slippery second floor and follow Lucky to the ambulance bay.
Chapter 5: Four aces open the roof gate. Exchange Mallory’s puzzlebox, Minspella’s ring, Griindel’s necklace and Lucky’s collar charm with Hyllindrix, one item per interaction. The ringbox is rejected: return to Minspella for the ring. Finish the friend quest before the roof.

Friendship scores and office key
Mary needs at least 8 points and more than Dr. Tetra. Each gives +1: apologize in 604, talk during Gus’s kitchen task, release the mouse, inspect GameGal in the maze, stay during her seizure, say you like the doctor during X-ray, and tell her about her leaking eye. Five party-menu conversations add up to +5; she gives the key automatically. Dr. Tetra needs at least 7 and more than Mary: kill the mouse, let him extinguish the maze candle, fetch seizure medicine, say you trust him during X-ray and lie about Mary’s eye (+1 each). Five conversations add up to +5; question him repeatedly on the stairs for the key.
Ollie’s missable quest
Meet Ollie in room 303. Find Mitzi in the kitchen and Ioro in the basement maze, in either order. Only after both are found will Ollie appear seated on the west building’s seventh floor; Ollie will not appear while Rune is in the party. Send all three to the shop. Once the roof dismisses your companions, return alone to talk to Ioro. Finish collecting friends while Mary and Dr. Tetra are still with you.
Entering the roof is a point of no return for collecting Ollie’s friends. Keep a separate save. The game is a Windows, macOS and Linux download; these routes were not personally replay-tested.
