@Vou It is a figure of speech. I think there should be all 3 of the Proton, Electron and Neutron group, and colliding them gradually makes all the elements in TPT in sequence :D
@Vou Thanks :D I think that there should be a ''particle mode'', so by pressing a button, enabling or disabling the Prot/Elec/Neut reactions, which means it can be completely disabled for older saves, removing the problem of breaking them :D
