Story and game background

 Welcome to the world of the universally famous Professor Aicrag, a.k.a Green Gravity Guy or G.G.G. for short! 

The Professor has spent the last 3 months searching  beneath the surface of the desolate planet ‘KNISSAH’ for very valuable minerals for his investigations. 

It is now time for him to return to his orbiter craft ‘The OTREBOR V’ which passes by KNISSAH’s atmosphere for just 5 minutes every 6 months. The Professor has discovered that there are small platforms of atomic oxygen known as ‘NWORBLA’ in the atmosphere surrounding KNISSAH. Using his specially designed jet-pack, and his strange jumping technique, the Professor must make his way up to the atmosphere where he can join the OTREBOR V.
