You are placed in a grid filled with stars which you can collect to increase your score.

Along the four walls of the grid are laser cannons which strafe back and forth, looking for any opportunity to blast you out of existence.

Collect all the stars whilst avoiding any laser bolts fired at you.

The closer you are to a cannon, the more likely its bolt will find its mark.

Hint: Try thinking of the arena are four separate areas - so rather than trying to keep tabs on all four cannons, you can concentrate on just the two that are in the 'quadrant' you are currently clearing.
