*** PLANETARY DEFENSE ***
(C) 2004 LYSOZYME

   Oh no!! A concerted attack by the evil aliens is underway!
Their goal: Destroy the Earth with their Planet Busters!!
Don't you just hate when that happens?
   Only your satellite stands between them and total destruction!
Destroy all incoming bombs and hang on as long as you can, 
for that high score!

   The Earth is in the center, and all bombs will come towards
it. With each impact, huge pieces are blasted off, until the
core is exposed. Once the core is hit, Earth is gone! Game over!!

   You may start at levels 1-10.

CONTROLS:

   Your satellite orbits the earth, and you aim your laser with
the onscreen crosshairs (aimed with your mouse). Fire your laser
with the left mouse button, and hold it down to keep firing. 
You have unlimited ammo, so blast away! But watch it, as the
satellite can be as big a threat as the enemy bombs! Don't shoot
the Earth as your laser will blow pieces off too!

   You cannot stop your satellite, but you can slow it down by
holding down the right mouse button. This can be handy if you
need to get some more firepower to a certain part of the screen!

   Your satellite will be destroyed if it touches a bomb or UFO.
You have unlimited satellites (there are no "lives"), but Earth
will be defenseless for a few precious seconds while your next
satellite appears.

   Press P to pause the game.

   Press ESCAPE to quit the game.

ENEMIES:

Regular Bomb   - This is your most common enemy. It can be hard
                 to hit, since it is not very big. It blows a 
                 moderate chunk off the planet if it hits.

Large Bomb     - The regular bomb's big brother, it's easier to
                 hit but causes way more damage to Earth if it
                 lands.

Doomsday Bomb  - A big bomb with a glowing red to yellow center.
                 It takes several hits to destroy but it must be
                 destroyed, because if it hits the planet it will
                 be destroyed! Even if it is intact!!

UFO            - A big saucer which shoots regular bombs. Takes
                 several hits, and can be a real headache!!

SCORING:

Regular Bomb  - 50 pts
Large Bomb    - 100 pts
Doomsday Bomb - 500 pts
UFO           - 750 pts
