Written in 1981 by J.D.S. Cranston, this 16K game is better than may seem at first.
You move thru a haunted park (from S to F) trying the shortest route, along the way creepy crawlers will appear.
Although simple, it plays rather well and in an addictive way. Remember this is for the ZX81 16K, in black and white from 1981, so don't go expecting something grandiose.
