About this game
If you're looking for a classic, straightforward idle game, this is it. The goal is simple: click to create atoms and let the black hole in the center swallow them. You earn "Neutronium" for every fusion. You use this to buy upgrades, get auto-clickers, and unlock heavier elements on the periodic table.
As you progress, the mechanics expand. Atoms start fusing with each other for bigger rewards. Random cosmic events like Pulsars, White Holes, and Wormholes will appear, rewarding you with rare resources like Dark Matter and Antimatter. Once your progress slows down, you can collapse the universe to gain permanent upgrades and start your next run much faster.
There are no confusing storylines, forced tutorials, or stressful mechanics. Just relax, buy your upgrades, and feed the black hole.
Core Gameplay: Clicking, buying upgrades, and automating your production.
Elements: Unlocking the whole periodic table, starting right from Hydrogen.
Cosmic Events: Random anomalies like supermassive black holes, pulsars, and cosmic storms.
Prestige System: A permanent skill tree to spend your points on when you hit a wall and reset your run.
Offline / Idle Progress: Drones and auto-generators keep the numbers going up even when you are not actively clicking
