Anomaly 404 scored 73/100 on Steam Analyzer — Good for a Psychological Horror capsule. Top priority fix: [uniqueness_polish] Incorporate visual anomaly indicators (subtle glitches, distorted elements, or layered reality cues) into the background to signal the game's core mechanic and differentiate from generic detective games.
