About this game

The playing field is the thing you spend

The reactor is a box whose walls are built from tiny cells. Atoms inside speed up under your hand, collide with each other and slam into the wall. Every hit earns energy and cracks a cell; every broken cell makes the chamber bigger. You chew through the reactor from the inside out, layer by layer, until the fuel rod runs dry.

Short raids, a long climb

  • Raids of 3-8 minutes. Fuel burns every second; clearing a layer refuels the rod.

  • A fusion ladder. Pack atoms together and they merge into heavier ones: protium, deuterium, tritium, helium-3, lithium-7, plasmoid.

  • A card draft inside every raid. Fill the charge and pick one of three cards; each card rolls common, rare, legendary or mythic.

  • A talent tree between raids. Four branches, twenty keystone mechanics that switch on new physics: black holes, portals, shockwaves, golden atoms, fuel veins and more.

  • Eight layers of wall, from lead to materials that do not exist in nature.

Active play pays

The reactor only runs while you are there: no offline income. Your hand is what packs atoms tight enough to fuse, and playing actively earns three to five times more than idling. Idle play still moves you forward, and the draft can buy some automation.

Everything is pixel art on an integer scale, with a synthesized reactor hum that follows the rhythm of the collisions.
