Step into the shadows and meet the Watchers. Umbra isn't just a puzzle game — it's a high-stakes journey through a world of daring heists, guarded by creatures that are all eye. Their glowing gaze sweeps the dark. When a Watcher blinks, its light goes out — and that's your window. Whether you're a casual gamer or a puzzle master, Umbra offers a fresh, modern take on stealth gameplay that demands logic, timing, and nerves of steel. You play Shade, a small piece of living shadow with one job: reach the golden Vault unseen. Every move counts. Get spotted, and the world freezes in dramatic slow motion as the Watcher's eye goes wide… Why You'll Love Umbra: Outsmart the Watchers: Five creature archetypes — sweeping Watchers, twitchy Scanners, three-eyed Sentries with no blind spot, prowling patrollers and worse — each with its own gaze to slip past. Their pupils literally follow you across the room. 100 Handcrafted Heists: Explore a vast array of unique levels — with the Black Ops expansions waiting for veterans. No two heists are ever the same. Daily Speed Rush: Test your reflexes in daily challenges. Chase your fastest times and earn rewards. Track Your Progress: Unlock achievements, boost your stats, and chase a perfect three-star rating on every heist. A World Made of Light: A neon-noir world of glowing gazes, living shadows, and slow-motion near-misses — optimised for a flawless experience on both iPhone and iPad. Can you escape undetected? The heist begins now.
