BARREL BARRAGE

Miguel van Smoorenburg ushers in a scenario of simian mayhem for the Sinclair
ZX-81.

The AIM OF the game is to get the keys which are displayed on the top of the
screen without losing a life. You lose a life if you get hit by a rolling
barrel but you are able to jump over such obstacles and only three at most
are present.

At the beginning of the game there is only one rolling barrel present. I f
you reach the top of the screen you can get a key. There are three keys at
the start of the game. When there are two keys left there will be two rolling
barrels and if only one key is left there are three rolling barrels. However,
if you manage to get your hands on the last key you will get a bonus of 100
points. Then you start again, with three keys and one barrel, but with one
difference -- the speed increases. Scoring is as follows: you still start
with five lives but this and the starting speed are adjustable -- it is even
possible to start off with 38 lives. The game has on-screen scoring and a
high-score.

Jump over a barrel:	 10 points
Grab a key:		 50 points
Get the last key:	100 points

----------------------------------

[The speed of the game is controlled by Rand (value). In my listing, it
[works as follows:

[290 INPUT SPEED
[300 RAND 1000+130*SPEED

[So the Rand has a minimum of 1000 and a maximum of 2950.

[Score, high-score and lives start off with a value given in the Basic
[listing in line 60. Score and high-score must be a number with a minimum
[zero, lives can be any characters between 0 and Z. Thus, it as possible to
[enter:

[60 PRINT AT 0,0;"SCORE:095870      HI:987320     LIVES: G"

[In this example lives will count down from G to 0. This is in alphabetical
[order.
