Game play:

The goal is to clear the level of aliens 
(not including mad bombers) by shooting them.
Protect yourself by enabling shields.  Shields
drain your energy but can absorb damage from
bombs at the expense of more energy.  You cannot
move or fire weapons when your shields are up.

Watch out for mad bombers!  If you destroy one,
you can equip your tank with one of the three 
special cannons that can only fire once.  The
more energy you have when you fire the cannons,
the more destructive their force.

The board can also be rotated for better viewing at times:
'g' rotates the board 90 degrees clockwise about the y-axis.
'h' rotates the board 90 degrees counter-clockwise about the y-axis.
't' rotates the board 20 degrees upwards about the x-axis.
'y' rotates the board 20 degrees downwards about the x-axis.
'b' rotates the board 20 degrees left about the z-axis.
'n' rotates the board 20 degrees right about the z-axis.

The movement keys and the x- and z- axis rotation keys will still map
correctly (e.g. 'a' will still move Shooter 1 left relative to the viewer)
after any rotation about the y-axis.

Game level Editor:

For each level, the terrain can be built from an associated
text file named "terrainX" where X denotes the level (0, 1, etc.).
This file contains a 11x11 floating point numbers that represent
the heights of evenly spaced points on an 11x11 grid.  The numbers
are not restricted to certain bounds in the file, but will be truncated
to fall between 0 and 2 in the game.  If no such "terrainX" file 
exists, the game defaults to using "terrain."  Otherwise, the 
terrain will be completely flat.
Enjoy!
