In this game, our hero is an Atomic Robot whose mission is to prevent the fusion of deuterium (²H) and tritium (³H) atoms. As the game progresses, hydrogen isotopes move across the screen and attempt to collide and fuse. Each successful fusion increases a counter. When 100 fusions occur, the game is over. The Atomic Robot's job is to: Intercept the atoms before they collide Break them into smaller fragments Continue destroying the smallest remaining fragments until no atomic particles are left on the field The goal: Ensure that no fusion takes place and no atomic particles remain.
