This multi-wave invaders/galaxians derivative in which you control a
laser base to shoot down the swooping nasties (sound familiar?) has a
glaring defect.
Symbol shift is used as the fire button, and yet if you accidentally
hit the space key (adjacent to the symbol shift) the game terminates
and you are presented with the operating instructions.
I felt like putting my foot through the screen when this first
happened and unfortunately it happened quite frequently with other
players too.
This mars an otherwise excellent game, with good playing rhythm
and lots of excitement. However, it should be relatively simple to
correct.
Apart from the keyboard problem, this offering compares favourably
with any game you would find in an amusement arcade.
