In the beginning, there was nothing. Then you tapped.
That single tap splits a quark from the void. From there you build, particle accelerators, proton baths, electron storms, each generator humming quietly in the background, stacking mass while you play or while you sleep. The numbers climb slowly at first, then fast, then in ways that require new words to describe.
As your mass grows, your universe evolves. Gas clouds condense into stars. Stars burn through their fuel and explode. Stellar nurseries seed the next generation of suns. By the time you reach a mature universe, you're sitting on billions of mass per second and the screen behind your atom looks nothing like where you started.
Thirteen stages in total. Each one feels different, looks different, and demands more than the last. You buy upgrades to multiply your generators. You buy more generators to afford better upgrades. The loop tightens.
Then comes the collapse. When your universe has lived its life, you compress it into a black hole. The extractor pulls antimatter from the singularity, a permanent currency that carries over across resets. You ignite a new universe with that bonus baked in, and the whole thing starts again, faster and stranger than before.
Do it enough times and you're not playing one universe anymore. You're managing a multiverse. Each universe you've built orbits in the background, adding a synergy bonus to everything. The more you've collapsed and rebuilt, the stronger each new run becomes.
There is no end state. There is only more.
