Suddenly, a bubble appears, you're trapped in a
walled surround, armed only with a zig-zag ray.
You fire. The ray moves slowly up the screen. The
bubble is hit - but it divides into two smaller
bubbles!
Each bubble splits in half three times before it
bursts, so a lot of bubbles end up bouncing around.
The bubbles move smoothly around the screen and
squash nicely as they rebound. You die if a bubble
bounces on you - and they can be very difficult to
avoid, especially as the response to the keyboard
is so slow. Using a joystick with ZX Interface II
is just as poor.
The first three stages have an increasing number
of bubbles, the fourth is a bonus stage, in which
you are immune from the bubbles and have a limited
time to score as many points as possible. After
that, the cycle repeats with faster action.
Graphics are smooth if uninspired, the bubbles are
all the same colour and sound is limited.
Bubble Buster is challenging at first, but I doubt
it will hold interest for long because there's so
little variety.
