Name of Software: Runaway Car
Author: Lardo Boffin
Release Date: 08/01/2017
Requirements (eg. 1K, 16K, AY Card, Hi-Res Scheme):1K, low res
Description:
Your car is leaking brake fluid on a long hill and it is getting steeper! Collect brake fluid to keep going as you crash when you run out! Your brake fluid warning light comes on when you are running low.

Avoid the oil spills as you will waste brake fluid controlling your car. How far can you get? 1700 meters or so should be easy enough.

Press a number from 0 to 9 to start where 0 is slow and 9 is fast.

Press a number once you have crashed to try again.

OK so seeing some of the other games on here which do more in less RAM I feel slightly daft posting this but it is my first game on the zeddy, first ever program written in Z80 and only the second game I have ever written so I guess its acceptable. Regardless I enjoyed writing it!

There are some issues I am working on with regards to the random number generation - it sometimes feels like an episode of Scooby Doo when Scooby and Shaggy are being chased past the same piece of scenery in an endless loop...

Also I need to get rid of the car's flicker when the screen scrolls down. Interestingly it doesn't flicker in the EightyOne simulator.

ZXPand-AY joystick support has been added. Note that I cannot test if it still works in hardware without the AY add on as I don't really want to take it apart... It works fine in EightyOne still though.

A single high score has been added as I don't think I have space for a table of them now!

BITD I often wondered why games on the ZX81 only used a small portion of the screen. I guess I know now!
