It's got eggs, birds and eventually the mothership, but with the exception of the birds flapping their wings, the graphics are boring. It is a reasonable copy, but by today's standards rather poor. The laser shield is almost too effective. There are several game/speed variations to experiment with, but on the whole uninspiring.
The speed of this phoenix version always takes my breath away, but I learned sometime back that it's actually easier to get better scores by playing the higher speeds. In the slower speeds you try to be accurate (never a good idea!) but faster you seem to get a better rhythm going. Sadly the graphics are small and dull and the overall impression is disappointing.
