This is an action arcade/platform game for Spectrum 48K (without music)/128K (with AY music) made using Arcade Game Designer 4.7 and AGDMusicizer II.
The main character is Travis Highrise, an interstellar renegade that was enslaved by aliens on the planet of Lavolatum.
He managed to escape, but now he has to flee from the planet.
He became aware, via rumours passed around by the other prisoners, of the existence of a spaceship. A speceship that was dismantled and hidden amongst the bunker-caves long ago.
So Travis Highrise has stolen a small spacecraft and must use it to collect the 7 parts of the spaceship ZUKINOX from inside the Caves of Lavolatum.
Unfortunately, the parts are scattered amongst the chambers of the alien bunker wherein he has been held captive - and they're crawling with hostile aliens! As well as the 7 parts, the spacecraft must also collect the 10 FUEL containers, necessary for Zukinox to take off and enable Travis to escape from the planet.
