About this game
The Single-Eye Nightmare is a first-person horror game where every step into the darkness could be your last. You’re trapped in the crumbling ruins of an underground temple, filled with twisting passageways, hidden chambers, and ancient mechanisms designed to keep intruders from ever leaving. To escape, you must outsmart deadly puzzles, survive dangerous traps, and avoid the watchful gaze of a monstrous Cyclops that hunts relentlessly through the tunnels. Survive the Temple Explore the maze-like environment to look for a way out. But be warned: the temple wasn't made with the intent to keep you alive. Crushing stone mechanisms, hidden spikes and crumbling ruins awaits you in every room you enter. Outsmart the Cyclops The Cyclops is hungry and won't stop at nothing to find your location. Stay dark areas, be weary of your footsteps and keep an eye out for the one-eyed monster lurking at every corner, searching for his newest prey - you. Solve Ancient Puzzles The temple expects a lot from travelers trying to survive. Manipulating water systems, pulling counterweight levers and solving combination locks are essential to get back to the surface alive.
