You have a sphere with a small rocket called the Spinoid and you need to hit other spheres as quickly as you can by spinning it around its axis. You get extra time when you hit a sphere and the game is over when the time hits zero.
(Spinoid actually means "spinelike", but in this context it is is rather the resemblance of something spinning or having an angular momentum.)
