In Alchemos, you'll pilot a Proto-Atomic Shell - an atomic-sized device capable of collecting and combining subatomic particles - to discover the elements. Explore weird and wonderful experimental worlds, and challenge your friends to beat your best times But beware, the particles you seek may be guarded by the forces of Dark Matter! As the Dark Atoms evolve to defeat you, you'll need to upgrade your Proto-Atomic Shell: dash and jump to safety, traverse quantum tunnels, emit particles to freeze your foes, or even annihilate them completely
