Sadly dad is no longer with us
but he was always impressed by my programming so I'm sure he would have liked the game so now I will finish it in his memory.
Have found some time to get back into this and am working on the baddie ai. Currently they move into the correct place to attack the player and face him as you move around. Need to work on the code as when there are three baddies on screen in the original, the swap places depending on who is closest.
Also noticed something I have never noticed before - you move up and down at twice the speed of the baddies!
Thought I'd post to assure all the project is still coming...
