Rework

I remade the entire game into a new engine

- The sound design has been improved with better sound quality and composing

- Graphically speaking, the game is a lot better than before, there are more detail than in the base version

The AI has been improved :

- on the existing behaviors, wich made it smarter

- With new behavior that make fighting more interesting

The game has now a progression system with different weapons (actually two but more in the future) wich require to have player levels to use them. These levels are acquire by doing actions (killing, escaping, surviving) in the game.
