D20&20

An entry for GDU Jam 4, focused on the theme of "2020". Set well after the great 2020 collapse, in a future where the ruins of the old world are explored as dictated by manuals left from the ancients, one broke adventurer sets forth to find an ancient artifact, the Vaccine, which is claimed to be able to cure any and all ills, and even restore the dead to life! Can you succeed at finding this VahSeen as the people of the world now call it, and escaping alive?
