Change Log V.16

• The Doom Guy’s head now turns in the direction of the damage received
• Add Pause feature during playing (escape or start)
• Add all skill difficulties, taking into account the number of monsters or objects in the level, damage management and the behavior of certain monsters

In I am a wimp skill, least monsters, lot of items, half taked damage, double ammo. Just chill.
In Hey, not too rough skill, less monsters, more items.
In Hurt me plenty skill, normal amount of monsters and items.
In Ultra-violence skill, greater amount of monsters and less items.
In Nightmare! skill, double ammo and full items, but agressives monsters can respawn. This skill is totally insane.
