Here it is!
'rubberball.arc' contains a demo version of the commercial game 'RUBBERBALL'.
It is written in the programming language Quick. I've uploaded the game to 
show you some features of that language.

The file 'rubberball.arc' is arced. Please use SUPUNARC to restore it. 

Then you can go on. Store all files i.e. 

RUBBERBA.COM
BALL.OBJ
BALL.ZS
BALL.SPL
LEV.1

on a single disk. Make sure BASIC is disabled and/or all cartridges are 
removed. Then use the DOS-command L to run the file RUBBERBA.COM
Leave the disk in your drive while playing it because it'll access 
the disk from time to time to load stuff.

Object of the game.

A small rubber ball is trapped inside an air conditioning system.
Use the joystick in port 1 to controll the ball. You can control the
horizontal movement of the rubber ball while it moves up and down just
controlled by gravity and slowed down by friction. Inside the maze you'll 
find some strange objects which will have some effect on the ball.
First of all there are some air pumps to be collected simply by making
the ball touch them. Be aware of nails. They'll puncture the ball.
In that case you'll loose one life of the small rubber ball.
On the way through the air conditioning system your rubber fellow will have
the opportunity to encounter pieces of chewing gum which will immediately
slow it down. Sometimes it is usefull, most of the time it isn't.
In some parts of the system there's an air current. It'll move the ball
in it's direction. Watch for it. 
Especially as a beginner you'll find yourself in a situation with no 
escape. In order to start over press the trigger. But everything has it's
price: you'll loose one life. You'll move on to another screen when all
air pumps have been collected.

As mentioned at the beginning this is only a demo version of the game
'Rubberball'. The commercial counterpart has more levels to play and
has a storable high score ranking list.

Have fun
