The Exit 8

A first-person puzzle game set in a looping underground passage. You walk through identical-looking subway corridors hunting for anomalies—subtle changes in posters, lighting, objects, or layout that signal something's wrong. Spot an anomaly and you backtrack; miss it and you advance, but the wrong choice resets your progress. The challenge is pure observation: noticing a flickering light, a misplaced sign, or an object that wasn't there before. No inventory management or combat. It's a short, focused experience built around pattern recognition and attention to detail. Works best if you enjoy spot-the-difference logic under mild psychological pressure, though the loop structure can feel repetitive once you've seen most variations.
