You are a surveillance operator in an underground facility. Compare two monitor feeds and find the anomaly. HOW TO PLAY - The top feed is the recorded footage, the bottom is the live feed. Tap the spots that differ. - You have a time limit and limited system durability (lives). Tapping a wrong spot costs durability. - Find every anomaly to clear the stage and move on. FEATURES - 3 sectors, 45 stages in total (Residential, Research, Reactor). The deeper you go, the shorter the time limit. - Anomalies include changed colors, vanished objects, and new objects. The smaller the difference, the easier it is to miss. - After each stage, pick 1 of 3 items. Spend the time bonus you earn to get stronger items. - Use hints and time extensions to survive tight spots. - Climb through ranks as you clear stages, and collect 30 achievements. - Track your daily streak. A "freeze" charm lets you skip a day without losing it. - No account needed. Your progress is backed up automatically in case you switch devices or reinstall. GOOD FOR - Fans of spot-the-difference and observation games - Quick, focused sessions - Puzzle lovers who enjoy a little tension NOTES - The app contains rewarded video ads, shown only when you choose to watch them. - The dim facility footage creates an uneasy atmosphere.
