LOG HOP
by Christopher Gibbs
from ZX Computing Oct/Nov.1984

Would-be lumberjack Christopher Gibbs sent us
this challenging program from Reading Forest.


A program which is as addictive as this and yet written in
BASIC is a rare thing indeed. Christopher has created a game
which is not only fast but fits into 16K with room for
titles as well! As can be inferred from the title, the game
involves jumping over logs and up through gaps to reach the
rings at the top of the screen.

You control a running man with keys 5 and 8 for left and
right movement and key 0 to jump. If you jump and miss the
hole above you, you will be rendered unconscious for a short
period of time and may fall through an approaching gap in
the level you have reached.

Three levels of difficulty are included and a hall of fame
chart for those who become adept enough to reach a good
score. Christopher says his highest score so far is 93%. I
admit to not getting any score at all - mind you, I wasn't
feeling too well. The score is worked out on the time you
take to reach the rings. So for a real test of your ability
type in this relatively short program - go on, hop to it!
