Echo Vault

Echo Vault is a cinematic spatial puzzle game where sound is your only way to see. Enter mineral-black vaults and use short sonar pulses to reveal the world around you. Every pulse exposes the geometry of the chamber for a brief moment — but it may also alert something listening in the dark. Listen. Reveal. Move. Survive. Navigate increasingly complex chambers by reading the space, managing risk, and finding the safest route forward. Features • 🎯 Sonar-based exploration — Reveal your surroundings one pulse at a time. • 🧩 Spatial puzzles — Learn the layout, plan your movement, and find a way through. • 👂 Risk & tension — Sound can help you… but it can also attract dangerous listeners. • 📱 Touch-first controls — Designed specifically for comfortable mobile play. • ♿ Accessibility-aware UI — Clear, focused interfaces designed to keep the experience readable. • 💾 Local progress — Your game progress is saved directly on your device. • 📴 Offline-friendly — Play the core game without requiring an account or constant internet connection. • 📢 Optional advertising — Ads are handled through the game's privacy and consent flow. No account is required to play. How far can you travel into the darkness before it hears you?
