General Hints

When using the keyboard, DON'T USE THE REGULAR ARROW KEYS!  Only use the ones
on the numeric keypad.  If you use the regular arrow keys, you will not be
able to run left and jump at the same time.  It's impossible to program
around that.  It makes many of the sequences SO much easier.

For combat -- build a few force fields, then start hacking away at theirs by
shooting it.  When yours gets low, don't hesitate to build a new one.  If you
use the "devastating" shot (read the manual), it will kill the enemy's force
field entirely.  But make sure you don't accidentally kill your own.

Don't get discouraged.  I know at times it seems this game encourages it, but
in reality, if you just do something a LITTLE different the next time, it
will probably work.
