Background Story
=======================

Life, life is a continuing loop of events. 

Life evolves, based on these events. 

Do these evolutions make life easier? 

If you think of an evolution in the sense that it's an upgrade. 

It does. 

This game is all about evolving, upgrading. 

Making life easier. 

But beware, when prey evolve their defense, 

hunters evolve their offense. 

This also will repeat itself, 

the loop of events of life.









How long will you survive? 

How far will you evolve?
