Astatine Dark

About this game

Astatine Dark is a timing and scheduling game set in a radioactive isotope
generator hall. Parent nuclides decay into precious daughter isotopes whose
activity climbs to a golden peak, then fades as the daughter itself decays.

Watch every activity trace, hit ELUTE inside the peak window and keep the
pump flow inside the green band. Elute too early and the batch is thin; wait
too long and the daughter decays away; run the flow wild and the column bed
cracks for good.

One pump serves every column, so stagger your rotation and never let a peak
pass unharvested. Deeper levels bring shorter half lives, sharper peaks and
more fragile beds. Earn coins, install reinforced beds, precision valves,
gamma lenses and yield amplifiers, and stock repair kits and feed cartridges
for the runs that go wrong.
