In this maze game, the idea is quite simple - all you have to do is collect the required amount of keys (the number needed is dispalyed at the bottom left of the screen) and then run to the door.
This is complicated by the fact that there are a number of Deadly Denizens of Dream World chasing you - if the Denizens don't get you then there is a fair chance the time limit will!
You take the part of Sleepy Joe who is in the middle of an endless nightmare. He can only escape by getting all the keys and moving on to another room. This is filled with even worse nightmares and Joe's only chance to wake up is to have a cup of black coffee which livens him up for a few seconds.
There are four different mazes, each with its own breed of Denizen. It makes use of excellent Mode 2 graphics but there is only a small quanitity of sound and no tune with the game. The characters are completely flicker-free. Apart from the lack of sound, my only criticism is that it takes a lot of practice to get Joe around a corner.
