I have managed to dig up this old game that I played in the early eighties unfortunately the guy who owned the game was a spoilt kid who would only let me play one game once a week. So I never got past level 5, now in my return I have progressed to level 8 but am stumped?!!! how the hell do you get through it. Also some advice on level 9 should I get there. I remember what level 10 looked like so l am not anticipating much trouble there.
