You control a constantly rotating sphere with a pointer. Click and hold down the left mouse button to stop rotating and move in the direction of the pointer. Stars are always shrinking and will gravitate towards your sphere when they are close enough. Try to collect the yellow stars to score points, the number of points depends on the size of the star. Avoid the red stars which subtract points from your score. In addition to stars, collect the green power-ups to assist you but watch out for the red ones.
