JetPac for the ZX81

Post by Bukster » Sun Sep 16, 2018 4:23 am

Here's my first new game post on this forum, a ZX81 version of the Spectrum game Jetpac I finished earlier this year. It has four types of alien and two ships to assemble. This version features re-definable keys and variable difficulty levels which the original game didn't have, so the ZX81 is ahead of the spectrum on those counts.

I had to take some liberties with the game play and alien design to make it playable. The spectrum version had a laser that zipped across the screen. That would have made the game too easy, so this uses minus signs like bullets. The difficultly levels adjust the number of aliens and bullets from four aliens/eight bullets to eight aliens/two bullets. Extra life at 2000 points. The bottom line of the screen tells you what your current task is such as assemble of fuel your ship etc.

Give it a go and see what you think.
