1988 Grupo Editorial Sygran(Spain)
by Javier Fafula and Carlos Coronel
Although simple looking (and average gameplay) this is mildly entertaining. Not as hard as usually games from Spain are, just the right amount of difficulty, which for personal computers I think works best.
You play a robot trying to escape an asteroid prison, to do so you must find the main 3 keys. A simple staight shoot 'em up a which a mix of adventure thrown in.
