There is no official wiki. Santiago Garcia’s itch.io page gives one plot sentence and a tag list. This page only keeps names I can point at: the blurb, a comment from Garcia, or a string in the Windows build checked on 2026-10-27. If a relationship is missing, it is missing on purpose.

People

NameWhat is confirmedWhat is not
StuartThe player, home alone for a day, invites his best friend. Named in the itch.io blurb.Age, surname, school, family. See Stuart.
EgbertBest friend. Spelled Egbert in voice lines and in Garcia’s replies. He puts on a mask.Whether the mask “is” him. Not defined.
Mrs. ParkerA woman on the phone. Lines include “Mrs. Parker.” and “Oh, hi sweetheart.”How she is related to Stuart.
CorkyA phone line asks “Is Corky home?”Pet, person, or joke. Do not pick one.

The house

The published screenshots show a living room, a kitchen with a back door, and a hallway. Videos also use a bedroom and the attic hatch. Scene names in the build are Attic, AtticTwo, and Credits. I am not drawing a floor plan I have not measured.

Objects

  • Telephone, backpack, Ouija board, guitar, a Pong television, math homework, pizza, chocolate, light switches.
  • Final buttons: GO UP and EXIT.
  • One day: ordinary afternoon, then a worse evening. That shape is consistent across the videos. It is not a multi-day calendar.
