Video Game Logic - Level grinding - Ancient Greek style

Sisyphus was a king who had a bad habit of murdering his guests, which was a major no-no back in ancient Greece (admittedly, it’s still kind of frowned upon). But what really pissed off the gods is how clever Sisyphus was. When he was first taken to Hades to be punished for his sins, he managed to trick Death into the chains intended for him, and then he escaped, while no one on earth died. And then when he was caught, he had his wife toss his naked body into the town square instead of giving it a proper burial; he complained about this to Persephone, and asked if he could go topside to scold his wife. Persephone said yes, and Sisyphus escaped again. Eventually he was caught and chained in hell, where he was forced to roll a boulder up a hill for all eternity.

that is where the game comes in.
