This is an entire mini-game, designed using the basic data structures.

You are a little dude, on an adventure. Your mission is to go around killing
guys and picking up weapons.

- Move around the map using the four arrow keys on your keyboard. Whenever you
  move in one direction, you turn to face that direction.
- You may only attack people you are facing. To attack someone, turn to face
  them, and press the spacebar.
- When you attack someone, your red "Attack" bar will go down. You must
  wait for it to go back up to full to attack again.
- When you are over an item, press Enter to pick it up.
  Weapons will be added to your inventory
  Armour will be added to your green armour bar.
- To use a new button, press the [ or ] buttons on the keyboard to scroll 
  through your inventory. The item in the red box is your current weapon.
