Trapped in a Game That Flopped

Apothecary Shari Azrael's life turns upside down when she suddenly realizes she's actually an administrator trapped in the RPG game "Save the Earth." Her only shot at returning to reality before her real body expires is to finish the game... which could've been possible were it not for the fact that "Save the Earth" is notoriously difficult in every single way! Can Shari successfully manage to use the perks of knowing the plot and gameplay to reach the ending before her time runs out? (Source: Tapas)
