Late one night on your way home you happen to pass by the eerie mansion of Dr. Joseph Agon, who happens to live in your neighbourhood. Being the careless type, he has left the front door wide open and you being the nosey type decide to take a butchers round his gaff.
In the living room, just behind the settee, you discover The Eidolon - a sort of space/time machine invented by Agon over a hundred years ago. Fortunately it was built to last and after tweaking a few knobs and levers you find yourself in a strange and mysterious world of cavernous mazes.
This is where the story ends and the game begins. Making your way around the labyrinth you must collect three jewels one red, one green, and one blue. Of course, it's not just a case of pick them up and thank you very much.
First you have to find them and there are a few problems there, namely trolls, rotofiles, puffer birds, etc. These little beasties complicate things by bumping into The Eidolon and draining its energy reserves. If all the juice runs out you end up back in Dr. Agon's living room - i.e. game over.
The creatures can be thwarted by firing spheres of energy at them. These come in four colours (a very colourful game, this) red, blue, green and gold, and can be found hovering around the maze.
Different coloured spheres have different powers. Blue ones give you more time by freezing The Eidolon's clock and gold spheres recharge your energy reserves. The green spheres have the power to transform one creature into another and red ones are essential for destroying the guardian of the jewel.
Once you have a jewel in your possession you must travel to the end of the cavern where you will find a statue of a dragon.
If you picked the right coloured gem the dragon springs to life and you must destroy it with a multi-coloured energy sphere cocktail.
If Dr. Agon's diary is to be believed there are seven levels, beyond which lives a dragon of truly horrendous proportions.
What sets The Eidolon apart from the numerous other maze games around is the structure of the maze and the quality of the graphics.
The maze actually looks like an underground cavern rather than the familiar breezeblock structure. It's also possible to turn by degrees and move in any direction which certainly adds to the sense of realism.
