It doesn't take much thought to realise that this is a copy of an
Atari game of similar sounding name. Unlike most copies, however,
this game is superb.
An alien bundle of energy resembling a bundle of sticks moves
about the screen. You try to pen it in by drawing a line about it with a
force field.
As you complete the perimeter, the area outside the field is filled
with colour. You must not pause whilst forming the force field or a
'ripple' will come and get you.
Similarly two quarks creep about trying to jump on you. When you've
covered at least 76% of the screen you get a new screen.
With each new screen the alien and the quarks become meaner and go
for the throat with increased alacrity. In fact, after about six screens,
life becomes positively impossible.
The game uses the bit mapped mode and is beautifully programmed. My
only complaints were the lack of a high score display and the lack of
clarity of the score.
If you have a C64, you must get Stix. It shows what a *real* game is like.
