* Background of the Game

The competitive environment of procreation has made sperm become terribly aggressive over the years.
According to a study, when sperm from another male is added to semen, over 50% of it will be attacked and killed within 15 minutes.
Mixing sperms of different males will cause some sperms to create a net-like structure to prevent other sperms from moving forward.
If that is not enough, they even launch a brutal attack on their opponents by piercing holes in their bodies using acrosomal enzymes.
