## Description
The tiny planet _Tai_ is the last outpost between the advancing Imperial
invaders and the planets of the Dorfain System and your mission is to defend
the planet until the Republican Battle Fleet arrive to destroy the invaders.
The Imperial invaders have targeted the planets core by sending ghostguards
and fireballs to destroy it, so in your ship viewed from above scrolling
vertically constantly, you must move left and right shooting anything that
doesn’t belong. If you touch a ghostguard, fireball or the walls then you lose
one of nine lives, but if you shoot enough of the enemy then you move through
the exit. You now join your Mothership in orbit around the planet and you must
move about in various directions shooting any enemy ships. Hitting an enemy
ship gains you fuel but getting hit reduces your fuel and when it runs out it
is game over.
