VOID SIGNAL — A Sci-Fi Horror Idle Game You are a lone operator at the edge of known space. Your station has detected a signal — a pattern hidden in the static between stars. It is not random. It is not natural. And it knows you are listening. TAP to decode data fragments from the void. UPGRADE your station with signal antennas, auto-decoders, and forbidden technology. UNCOVER 25 transmissions across 5 acts of an original sci-fi horror narrative. WATCH as the proximity meter rises — something is approaching through the darkness. REBOOT your station when the entity arrives, earning Void Echoes that make you stronger with each cycle. FEATURES: - Atmospheric idle gameplay with a haunting original story - 8 upgradeable technologies from Signal Antenna to Singularity Core - Proximity system with escalating horror effects — glitch visuals, CRT scanlines, whispered voices, phantom messages - Prestige system with Void Echoes, Encrypted Shards, and permanent upgrades - Black Market with cosmetic terminal themes and ad-rewarded power-ups - Multi-layered audio: ambient station hum, proximity drone, whisper loops, and SFX - Offline earnings — your station keeps collecting while you are away (up to 8 hours) - Retro terminal aesthetic with phosphor green VT323 typography The void is patient. It has been waiting since before the stars were born. You received a signal. You should not have answered. But you were always going to. [ SIGNAL DETECTED ]
