Atom 118

Build every element of the periodic table, from hydrogen to oganesson, against the clock. Drag protons, neutrons and electrons into an unstable atom that reacts to every particle: rush it and it collapses. Every element you complete adds seconds to the clock while the music adapts to your playing style. Face radioactivity from technetium onwards. Free demo up to ruthenium. One purchase unlocks the rest. No ads, no subscriptions and no data collection.
