Blocked Under Ground

Read full description

Bei einem U-Bahncrash werden Menschen im unterirdischen Tunnellabyrinth eingeschlossen. Verzweifelt suchen sie einen Ausweg, während Starkregenfälle den Untergrund fluten. Navigiere das Tauchboot durch das Tunnelsystem und finde heraus, wie Du ihnen helfen kannst. In diesem Audiogame siehst Du nichts. Anhand der Geräusche und Sonartöne kannst Du das Tauchboot navigieren. Über Funk bekommst Du Informationen von der Rettungsleitstelle. Die gefährliche Unternehmung ist eine extreme Raumerfahrung und von Deinem Geschick hängt das Leben der im Untergrund eingeschlossenen Menschen ab. Dieses Audiogame ist Teil eines intermedialen Audiodramas, das mit Hörspiel und Audiowalk weitere Zugänge in die Handlung anbietet. Das Game wurde von Regine Elbers als praktischer Teil ihrer künstlerischen Forschung am Experimentellen Radio der Bauhaus-Universität Weimar entwickelt – in Zusammenarbeit mit dem Bayerischen Rundfunk, gefördert von Center for Technology & Society (CTS) Wien.

About

Gravity Whisper

Features
Read full description

A comet drifts through the cosmos, far from home. Its only hope? You. Gravity Whisper is a physics puzzle game where you create gravity wells with a tap of your finger. Pull, slingshot, and guide a wandering comet through increasingly complex space environments — past black holes, through wormholes, around orbiting planets, and across tidal streams. SIMPLE TO LEARN, HARD TO MASTER Tap and hold anywhere to create a gravity well that pulls the comet toward it. That's it — no buttons, no joysticks. But be careful: touch the comet with your finger and it's gone. Every level is a puzzle of timing, trajectory, and patience. 360 HANDCRAFTED LEVELS Journey through a massive campaign of hand-designed puzzles, each with a unique name and personality. From "First Light" to "Infinite Reflections," every level introduces new spatial challenges that test your intuition and skill. EVER-EVOLVING MECHANICS What starts as a simple physics puzzle evolves into something far deeper. New mechanics are introduced gradually: • Black Holes — gravitational traps that devour the comet • Wormholes — teleport across the level in an instant • Gravity Ropes — tethered obstacles that block your path • Moving Planets — orbiting bodies that patrol the void • White Holes — repulsive forces that push the comet away • Gravity Lenses — bend the comet's trajectory mid-flight • Pulsars — blinking hazards with deadly timing windows • Asteroid Belts — rings of spinning rocks • Magnetic Gates & Switches — toggle barriers on and off • Nebula Fog — hidden dangers shrouded in mist • Tidal Streams — directional currents that sweep the comet • Mirrors — bounce the comet off reflective surfaces EARN STARS, UNLOCK GATES Complete each level before time runs out to earn up to 3 stars. Finish faster for a higher rating. Every 10 levels, a Star Gate challenges you to prove your mastery — earn 90% of all available stars to proceed. BEAUTIFUL & ATMOSPHERIC A soothing cosmic aesthetic with smooth gradients, glowing particles, and poetic level names that tell the story of a comet finding its way home. FEATURES • 360 unique puzzle levels • 12 distinct game mechanics introduced progressively • 3-star rating system with time-based scoring • Star Gate checkpoints every 10 levels • Offline-ready — no internet required to play • Haptic feedback for an immersive experience • Localized in 40 languages • No ads.
