About The Long Gate

The Long Gate is a single-player, first-person puzzle game in which you explore ancient caverns and natural oases on a mission from the enigmatic creators of the place. You repair ancient circuits, learn to solve digital, analog and quantum puzzles, and investigate what happened to the creators.

Puzzles and exploration

Nearly all the puzzles are based on real-world technologies. They include accurate depictions of quantum circuits and a 4-bit quantum computer, verified by scientists at D-Wave Systems. You learn the basic principles behind each puzzle type as you progress; no technical background is needed to finish the game.

Levels and many puzzles can be completed in any order, and many puzzles have more than one possible solution. Mastering a circuit type provides keys to new areas and secrets. If you get stuck, you can explore elsewhere and return later, or turn on hints in the settings menu; the hints have optional levels.

Soundtrack

The game features an original soundtrack by musician Nick Newman.
