Angstraum

"Angstraum" (lit. 'fear space') refers to a place or situation that induces fear or discomfort, often associated with a sense of threat or unease.

A walking simulator with horror elements, inspired by the Backrooms and anomaly games like The Exit 8.
Gameplay
Trapped in an endless loop of an old German railway underpass, you must use your memory to escape. Explore your surroundings, remember every detail, and watch for anomalies to find the exit.
Anomalies
Anomalies are changes in the original environment – sometimes subtle, sometimes deadly. Up to 50 unique anomalies await to be found. The further you go, the harder it becomes to recognize them or escape their threat.

The Path to Freedom
But not every section contains an anomaly. The decision lies in your perception:
Anomaly found? Turn back.

No change? Move forward.

Reach ten correct decisions and escape the loop. But beware: A single mistake – or your death – will send you back to the beginning.
