You can tell you're tangling with Galakzions rather than Space Invaders because the hostile aliens move
more unpredictably - and you have no bases to cower behind. The aliens at each end of the advancing
horde tend to peel off and dive down towards you. When they do, all you can do is keep out of their way.
You can't really win this kind of game - it's more a matter of how long you can stay alive.
Mikro-gen's version has simple, effective graphics. I particularly like the continuously scrolling stars
in the background.
It's a game for one or two players, using either keyboard or joysticks, both of which give you easy
control over your ship. There's a high score option, and you can choose your playing speed.
For all that this is a neat interpretation and will probably get a fair amount of play, though, I feel
that software companies ought to be thinking in terms of more elaborate plot and presentation.
