Okay, we're finally on chapter five, and now we'll write something fun, not serious and boring. Before the Great Flood, when our ancestors were riding dinosaurs, building
pyramids, killing African men and mating with Asian women, people didn't have dedicated nor integrated graphical processing units, called GPUs. They only had their terminals,
built inside some of their spaceships. And what did they do with them? They played terminal rogue-like games, similar to those that archeologists discovered in ancient Egypt,
Syria, Sumeria, Greece and Atlantis. They were reconstructed around 50 years ago by some guy that made the game Rogue. So, all those myths, sagas and legends about Anubis,
Gilgamesh, Achilles, Inana, Gaea, they were just playable characters or main characters in those games, with different statistics, skills, attributes and back-story. Now, lets
make a simple terminal rogue-like game using what we wrote in previous chapters.

First of all, lets talk briefly about keyword 'typedef' and why I hate to use it.
