The primary objective was to give a narrative framework to a fun, light-hearted gameplay: throw characters into the scenery to obtain the highest score (the most broken bones). 

The game itself already had a parodic tone, offering a surprisingly cathartic experience. Catharsis was the starting point for our discussion of "purification" and "redemption". Add to this train of thought bodies falling from the sky, and you're on the threshold of theology. So why not parody it? 

Fallen Angels. Fallen angels. People who have to purify themselves before they can enter Paradise. But how? Like all penances, through suffering.
