Spot the anomaly. Trust your gut. One mistake sends you back to car one.

Each run drops you into the same train car — but something's subtly off. Compare it to what you remember as "normal." See a change? Go back. Looks clean? Move forward. Get it wrong, and you're back at the start.

• No HUD. No hints. No counters. Just your attention, building a streak of correct calls — one car at a time.

• KEY FEATURES

• Fixed scene, infinite variation — anomalies never repeat the same way

• Zero UI — nothing between you and the pattern

• Instant feedback loop: decide, see result, adapt

• Short sessions built for "one more run"

• Light parallax and atmospheric train sound design
