The ancient and alluring caves of The Long Gate are filled with the remains of mysterious mechanisms. Exploring the labyrinth of caves and interacting with this mysterious mechanism will prove vital to master the three types of puzzles based on digital, analog and even quantum circuits. To ensure that quantum puzzles accurately represent actual quantum circuits, developer David Shaw has partnered with quantum computing company D-Wave. The secret of mysterious caves and ancient mechanisms lies in completing various circuit-based puzzles. With players free to explore how they choose and solve puzzles, the key to unlocking the secrets of The Long Gate remains with them.
