I remember a game we used to have in the eighties when I was a young kid. We had a pc with msdos, a monochrome screen, the big thin floppy disks. The game as i remember had a black background. I think you controlled a maybe triangle shaped thing that could shoot. Shooting was done with the space bar. There where different enemies in different levels. One was with a sort of round white or yellow (because of our screen) colour. They moved very shaky as I recal. Another had enemies I think with lines maybe resembling a line drawing of a bird. The screen itself didn't move. Just the enemies and your triangle shooter thing. I'm not sure if you could only move sideways or up and down as well. I think you needed to kill all enemies and in between the levels was something else. Left and right where white or in our case yellow walls. There was a black winding corridor in the middle. Your triangle would start at the bottom of the screen and move upward, pretty fast I think. You had to manoever and avoid hitting the white walls on the right and left. I've never seen images of this game but I have some stuff pretty clear in my mind. I think the enemies made some weird sound as well but it's not clear. There where no sound cards yet at that time. So it was sound from the pc speaker. The game was probably on 1 floppy disk. A mouse was also not common yet at the time. Everything was done by typing. You cd a:\ dir/w djskadla.exe etc. My mother used wordperfect where you also needed to use codes or something to for example write in bold and stuff. That's for which time to think of. Anybody know what I'm talking about?
