Click to place. R to rotate. Del to remove. Scroll to zoom. Drag to pan. Space to pause.
Sources produce level-1 atoms onto an adjacent conveyor (conveyor must face the source). Fusion takes two same-level atoms from two sides and outputs one atom of the next level (1+1→2, 2+2→3, 3+3→4). Deliver level-4 atoms to a Sink to earn points. Splitter sends one belt to two outputs; Merger combines two belts into one. Prestige resets the grid and gives a permanent production bonus.
