The best way to run the game is in full screen performance, or full screen compatibility, whichever works best. Note that I've moved the taskbar to the top so I don't accidentally open programs in my zeal to kill aliens.
Level 1, Wave1
On this one, just keep shooting until you kill 'em all. I usually follow
them to this side, because they move to the right first. I like to stay
at the very bottom of the screen, it gives more time to think of where
to go to avoid their bombs.
Wave 2
Here comes the power-up... Get over there to get it, it's one of the
most important aspects of the game. Just position your ship beneath it
and let it hit you.
Wave 3
Start this wave with your ship in the middle, then try to shoot the
lowest ones first (the ones closest to you). In doing this, it takes longer
for their bombs to get to you, thus giving you more time to duck out of
the way. You can also follow the main group to the side and pick 'em off
"enmass".
Wave 4
Notice that I've started shooting from the one side and traveled to
the other, I do this often. It enables you to hit and kill or weaken the
other ships before they have a chance to get you. If you leave a bunch
of shots in the air before the new wave arrives, you increase your chances
of escaping the bombs from enemy ships by getting rid of them ASAP.
Wave 5
Once again, move from one side to the other, I paused this one very
shortly after the new wave arrived, note that there's already ship(s) missing,
and one that's going to be "one hurtin' puppy". Since most of the alien
ships are going to the right, I'll sit on the right margin for a while
and pick 'em off quickly. The best strategy is to get as many as fast as
you can, 'cause, dead ones can't hurt you...
I'll be updating this and the other pages after I get the lot online.
Don't worry, I'll get around to linking all the pages from any page
later, first things first.
