5.) What sprites do when shot and sprite strength:
*****************************************


These behaviours are for what happens when the sprite is killed either by shooting, 
contact with Keen or other sprites, or when programmed to disapear. This is followed
by the vorticon strengths [the only adjustable strengths in the game] 

Dead sprites will still disappear when they go offscreen no matter what behaviour 
they have.

The behaviour 'Do nothing' is used for dead sprites and means Keen can't shoot or 
interact with them. Changing this will mean Keen can say, shoot a dead sprite, or 
that the dead sprite actually becoes a live one [But the shocked sprite will show 
first, looking like a transformation, also the created sprite will be immortal] A 
good patch is to make a dead sprite spawn a shocked sprite.

Giving a sprite the Do nothing behaviour will make it immortal.

The four icecubettes' behaviour cannot be changed except to $4A $00 without crashing
the game, and the robot's and Keen's shots are difficult to patch, often crashing 
the game. [Don't even *think* about patching the Chain zap/zot]

Any Vorticon under a falling block chain is a Vorticon commander, as are ALL 
Vorticons in the Vorticon commander level

The 'what kills what' section has the sprite properties of sprites that kill another sprite.
For example Keen's shot ($0A) kills most sprites and has an entry for each one. The $3D\$3F
part is because sprites with no strength need $3D whereas those that have strength use $3F.
