關於此試玩版

Backrooms: Lost Dimension is a narrative-driven single-player horror game: explore unsettling liminal spaces, solve environmental puzzles, and survive increasingly dangerous encounters.

Key features

  • A “liminal” horror atmosphere with a constant sense of tension.

  • Unique puzzles integrated into the environment (not just “keys and doors”).

  • Guided progression: the game introduces mechanics step by step.

  • An original story and levels with distinct identities.

  • Free post-launch updates with new levels that expand the nightmare.

What the Demo includes

The Demo includes the first three levels of the game, designed as an introductory experience to immerse you in the atmosphere and core mechanics right away.

  • Content: Level 1 / Level 2 / Level 3 (intro + escalation).

  • Estimated playtime: [15–35 min] (depends on time spent on puzzles).

  • Goal: get familiar with exploration, puzzles, and rising tension.

  • Saves: [Progress does not carry over] to the full version.

If you enjoyed the demo, add Backrooms: Lost Dimension to your wishlist to support development and stay updated.
