About

Annoying Ghost

Features
Read full description

Annoying Ghost is a 3D-audio game you play with your ears, not your eyes. Put on any headphones and a mischievous ghost comes to life all around you — whispering in one ear, cackling behind you, going eerily quiet, then swooping in. Your phone is your bat: point and swing exactly where you hear it to knock it out. The sharper your aim, the higher your combo. It's fast, funny, and genuinely spatial. No staring at a screen — just listen, swing, and send that pesky spirit flying. FEATURES • True 3D spatial audio — the ghost moves in a full sphere around you with AirPods/Beats head tracking, or a reliable arc on any headphones. • Swing to strike — motion-based combat reads where you actually swing your phone. • A cast of characters — a giggly imp, a squeaky baby ghost, a grumpy grandpa, or "Digi-ghost," who taunts you in your own cloned voice via Personal Voice. • Escalating waves — every ghost you knock out brings a faster, twitchier one. • Combos, near-misses, knockouts, spring launches, and creepy ambient surprises. • Haptics and glanceable color feedback for every hit and miss. HOW TO PLAY 1. Put on headphones (required — it's a 3D-audio game). 2. Hit Play and listen for the ghost. 3. Point and swing your phone right where you hear it. 4. Land hits, knock it out, and survive tougher waves. REQUIRES • Headphones or earbuds (any will do; AirPods/Beats add head tracking). • A little space to swing safely. Clear your space, mind your surroundings, and keep a firm grip on your phone. Happy hunting.
