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 ]

Primordia Lab is a physics sandbox where you start with a handful of atoms and end up somewhere no one expects. Paint elements into a living, simulated world. Water flows, fire spreads, metals melt, storms rain, and every pixel obeys the same rules. Mix substances to discover new ones, log your findings in the journal, and spend your earnings on new tools for the lab. WHAT MAKES IT DIFFERENT - A real falling-sand simulation: heat, pressure, electricity, magnetism, and gravity all interact - Discovery-driven progression: combine what you have to reveal what comes next - An idle economy that keeps working while you are away - Research programs, blueprints, and a technology tree that unlock deeper systems - Ollie, the lab's assistant, shows you around and tells the lab's story - One shared in-game planet: every scientist's work adds up to restore it, stage by stage - A long arc of ages that starts with chemistry and goes much further than you think BUILD REAL CIRCUITS Wire batteries, switches, motors, and lamps into working DC circuits. Voltage, current, and resistance behave like the real thing, so the electrical bench is a little physics lesson in disguise. CAUSE ABSOLUTE HAVOC Drop a meteor. Light a wildfire. Place a black hole and watch it eat your whole world. LEARN AS YOU PLAY Long-press anything to read its real history and science in the Info panel. Primordia Lab is free to play. Optional purchases support development, and every ad is opt-in.
