SPACE ARMADA: "Practice" vs "Game" ?

Archived from groups: rec.games.video.classic (More info?)

What is your favorite way to play Space Armada? On one hand, "Game" is
far more interesting, what with the different kind of bombs, etc. The
trouble is, that at some point the game stops being so much fun and
gets downright frustrating - namely when all of the invaders are
invisible.

The "Practice" mode is more like your straight Space Invaders, only one
type of bomb, and no invisibility. For a while it "seems" the game is
the same screen after screen (with the potential of an endless game
such as the case with Atari's "Space Invaders"..), but the practice
mode actually DOES get harder: the invaders do start moving at faster
speeds than they did at the beginning, making it more difficult to
clear each consecutive screen. This is illustrated by the fact that the
invaders begin moving so quickly that you can take out THREE invaders
with one shot, whereas in earlier screens you can take out two at most.

What are everybody's thoughts on this?
