Rings

In the year 3256, mankind has expanded into space. People live in giant space stations called RINGS. It would be all well and good if it weren't for those meddling aliens. Some say we have disturbed their natural habitat. Whatever, we must destroy them.

Your goal is to get the highest score. To do this, survive as long as possible by destroying aliens, avoiding the red balls they throw at you, collecting the yellow balls to restore your shield power, and rescuing stranded space people. Both red balls and collidign with the terrain cause damage to your shield.

Use the D-PAD to change your horizontal and vertical position relative to the ring's surface.
