The controls are incredibly simple – hop left or hop right. At the top of the screen is an icon indicating the strength of the hop (HI/LO). 

A flea called Bugaboo has fallen into a deep gorge, and it’s your job to get it out as quickly as possible, reach the top of the cavern in which it has become trapped. 

The cavern is made up of various ledges and platforms which you can use to work your way to the top.  The task is complicated by the fact that 2 minutes are available for the mission and the sample of the alien life form, which is concentrated in 3 eggs, must be brought to the surface.
