The only game with inverted-volume mechanics. Sneak through three levels (museum 🏛️ · mansion 🕯️ · lab ⚗️), dodge 👁 patrols, 😴 sleepers and 🐕 watchdogs, collect 💎 diamonds, chain 👻 ghost streaks and use 💨 smoke bombs + ⚡ noise masks.
Grant mic permission — audio stays 100% in your browser.
Character auto-scrolls; red circles = 👁 patrol, purple = 😴 sleeper (ultra-sensitive), orange = 🐕 watchdog.
Inside a zone: whisper softly! Volume fills the detection meter; rate depends on guard type.
💎 Grab diamonds between guards (+25). 👻 3/5/8/12 streaks award bonus XP.
💨 Smoke bomb auto-fires every 4 passed guards (threshold doubled). ⚡ Thunder & 🚂 trains mask your noise for 2 s.
Meter at 100% = busted; the guard yells a funny line at you.
Accessibility
All games also work with the keyboard if no microphone is available or you don't want to make sounds. Audio is processed locally only — no recording, no upload, no cloud.
