Santiago Garcia did not publish a manual on itch.io. This index is the map I built after watching two full videos and reading the Windows build’s UI strings. It is a chapter skeleton, not a claim that every fuse and key has been solved. Where a step is only a community label, I say so.

Controls I can support

  • WASD moves. The mouse looks. Both videos play that way.
  • C is the interaction key suggested by an on-screen prompt and by a cKey string. Confirm it in the pause menu if your build differs.
  • Esc opens the menu. I did not see a difficulty option or a chapter select.
  • Comments ask for a checkpoint so people can see both endings. That request is evidence the build they played made them replay.

Day to night

Midnight Matinee Games marks a 21:49 video as Home Alone at 0:00, Ouija Board at 5:01, Attic at 14:47, then the two endings. The Demo Daddy’s 33:09 video uses different titles for the same arc: being home alone, inviting the friend, something feeling off, exploring the house, and a climax. I treat those as two witnesses to one afternoon, not as official chapter names.

Interactions the build names

  • Pong on a television (PongMinigame, Eg-Score).
  • A guitar minigame (MinigameSong) and a math homework prop (MathHomework).
  • Pizza and chocolate pickups, a backpack sequence, sitting on a sofa or chair, light switches, a telephone, and an attic hatch.
  • No combat loop showed up in either video. I am not going to invent a weapon.
  • Walkthrough

    Chapter times and the final GO UP / EXIT choice.

  • Endings

    What each route shows, and what is still unproven.

  • How long

    Two verified video runtimes. No developer number.

  • Is it scary?

    Jumpscares, darkness, Ouija, and who may want to skip it.
