to two players |
There are no life
counters |

counter |

no Skip a Rack feature |

The game display
kernel is completely different and appears to be
unoptimized. Everything flickers quite badly |
The player's ship is
green instead of yellow or blue |
The Sentinels are
yellow and shaped differently |
The energy cells are
gray (or green depending on the level) and aren't made
of two different colors. |
The fireballs are
completely different looking. They're made of
two different overlaid sprites and look like an orange
blob with yellow 'electricity' over it. |
There is a new type of enemy that looks like a
stationary fireball. These were in the arcade
game (looking like little whirlpools) but were removed
from the final. |
The first player uses the bottom score while
the second player uses the top score. This is
the opposite of how it is in the final. |
The sounds are different. The start of
rack music and death sounds are completely missing. |
Holding down the reset switch allows you to
cycle through all the levels |
There is no demo |
The controls aren't quite as tight as the
final version, causing the player to overshoot the
rows constantly |
Occasionally an energy cell won't register as
being touched |
