BLIND ECHO - Navigate the Darkness The world is dark. You can't see anything. A tiny dot of light - that's you. Somewhere in the void, obstacles are rushing toward you. You can't see them... unless you listen. Every few seconds, a sonar pulse erupts from your position and ripples outward into the darkness. For a brief moment, the obstacles flicker into existence - then disappear back into the black. Can you memorize what you saw? Can you dodge in time? ------------------------------ HOW TO PLAY ------------------------------ - Tap the LEFT side of the screen to move left - Tap the RIGHT side of the screen to move right - A sonar pulse fires automatically - use those glimpses to survive - You have 2 lives. One hit turns you dim. Two hits ends the game. - Survive 10 seconds after getting hit to recover your second life. ------------------------------ FEATURES ------------------------------ - Minimalist atmospheric design - Sonar-based visibility mechanic - unique survival gameplay - 2-life system with auto-regeneration - Progressive difficulty - the longer you survive, the faster it gets - 3 obstacle types: horizontal bars, vertical pillars, and L-shapes - Persistent high score tracking - Original dark ambient soundtrack ------------------------------ THE CHALLENGE ------------------------------ Speed increases every 10 seconds for the first 100 seconds - then continues to scale.

Read full description

A puzzle saga from the heart of an ancient mythology. Gökçe is a young girl. When lightning awakens her, she sees the sacred tree that binds the worlds together: Ulukayın. Its roots reach down into the underworld — Erlik's realm of shadow — its trunk holds the earth, and its branches rise to the upper world, to Ülgen's light. Seventeen layers in all. Each layer a realm of its own, each with its own story. Gökçe must climb them, one by one. Each layer is filled with puzzles to solve — match to clear each level, and clear levels to rise to the next layer. Every new layer brings a new god, a new spirit, a new secret. - CLIMB THE WORLD TREE From the roots to the crown, ascend all seventeen layers. Each one opens its own landscape and its own legend — from the shadows of the underworld to the light of the sky. - HEX MATCH-3 — FIVE ANCIENT ELEMENTS Not your typical square grid. A hexagonal board with many elements: Not only stone cut gems. Fire, Water, Earth, Wind, and Sky and more. Every combo is a legend; every cascade, a miracle. - COLLECT MYTHIC SPIRITS Eagle, Stag, Bear, Simurg, the White Goose and more… Gather the legendary spirits. Each grants you a unique power. - MEET THE GODS Umay the warm Mother, Ay Ata the moonlit mystery, Mergen the wise, Kızağan the fierce, Ülgen the radiant. Each deity is a step in Gökçe's climb. - WHAT'S INSIDE • 17 layers, 800+ original puzzles • Original soundtracks • A deep story told through cinematic cutscenes • Cozy, no-pressure play - READY? Gökçe Deniz means "Celestial Sea" — the human echo of the primordial ocean. Walk with her. Ulukayın awaits. A mythology puzzle you've never seen — now in your hands.
