The Queen of the Cosmic Wartoads has been abducted and imprisoned by
THE RYGELLIAN SLIME BEASTS, their deadliest foe.
Chained beneath the murderous Sludge Saw in the King's chamber and
transformed into an apparition of horror to the Wartoads (namely a
human female), her fate is measured by the descent of the blade, which
unless stopped will slice her in two!
The task of rescue has fallen to you, the most heroic Cosmic Wartoad,
to traverse the Rygellian Time-Void, reach the Slime King's lair and
dismantle the deathly machine with your Cosmic Tool Kit.
The eight pieces of the Tool Kit are scattered around the Time-
Vacuums of the Void and must be collected en-route to your goal.
They are: Intergalactic whisk, Chronosynclastic stanley knife, X-Ray
binoculars, Stellar fish, Death-Ray smutt gun, 3 million megawatt
light bulb, Cosmic axe and a Zippo lighter.
The reward for success is the hand of the Queen and all her Kingdom;
the penalty for failure is death!CosmicWartoad

The various elements and objects in the game are described in the
following notes; read thoroughly for maximum playing power.Screen Shot 2016-08-05 at 16.46.21

In the Rygellian Void, time and space do not operate and traversing
must be achieved by moving between Time Nodes (Oases in time). There
are 64 of these Nodes in the Void, interconnected by Vacuums where the
monstrous servants of the Rygellians lurk ... bent upon destruction.

The only real measure of time and space is in fact your destination -
the King's lair. This contradiction is demonstrated on-screen by the
use of "Time Windows", superimposed upon your "Real" when and where.
You traverse the Void by moving from one window to the next and during
the transition between windows will be afforded a moment to survey
events in the King's lair, in particular the progress of the Sludge
Saw as it moves inexorably towards the Cosmic Queen!Screen Shot 2016-08-05 at 16.46.51

This is a map of the Rygellian Void in the form of a grid, each square
representing a Time Node.
The grid is colour coded to demonstrate the different properties of
different Nodes.
Green:      The time node currently occupied.
Purple:     Power node at the end of the time vacuum (leading to one
            of these is a Lily Power Window, for recharging your
            weapon ... see under "Constant Recoil Alpha-Pellet gun").
Yellow:     The bottom left-hand corner of grid - your destination
            (the grid next to the Slime King's lair).
Red:        Locked time tunnel.
White:      Unlocked time tunnel.
Cyan:       Ordinary "Node".

In the Time-Grid window you control Cosmic Willy (a tadpole which acts
as a cursor), allowing you to select your next Time Node. Move Willy
over your chosen Node and press fire (or key equivalent) and you will
be thrust into the Time Vacuum between your present Time Node and the
selected one.
(N.B. You cannot travel to any Node at will however, only those in
immediate proximity: Up, Down, Left or Right of your current Node
(Green grid square) or Willy will voice his displeasure!)Screen Shot 2016-08-05 at 16.54.16

The path between Time Nodes is a "TIME VACUUM". There can be one, two,
three or four separate Time Windows and each of these contains one of
three different foes ("The Rygellian Nasties").
In each Time Window you must engage the nasties and fight to the death
... yours or theirs. If you succeed you will be transported to the
next window in the Time Vacuum, or if it is the last one back to the
Time Grid Window at the node you have reached. If defeated you'll be
transported back to the Time Grid Window at the Node you tried to
leave (and also lose a life). If you lose all three lives you'll be
returned to the beginning of the game with three new lives, but
remember the Sludge Saw has been descending continually so now you'll
have to be that much faster!

The eight elements of the vital kit are to be located in the Time
Vacuum Windows, as are the keys for the Road to Nowhere and Somewhere
(explanation later).

The main defence against all enemies is your Constant Recoil Alpha-
Pellet Gun; to operate simply press fire (or key equivalent). The
weapon must be periodically recharged and your ammunition status is
displayed at the bottom of the screen. When your firepower reaches a
critically low level the status strip will flash - if the gun's charge
runs out completely you suffer the loss of three lives simultaneously!
However, there are Power Nodes where you can replenish your weapon
(these are coded purple in the Time Grid).
The Time Vacuum leading to a Power Node always ends with a Lily Power
Window and it is here that the gun is replenished (there is no
restriction on the number of times you may visit a particular Power
Node).Screen Shot 2016-08-05 at 16.54.43

There are three types of enemy which are colour-coded for their grade
of nastiness (four categories): white, yellow, magenta and finally the
most nasty, red. (The higher the grade the more difficult to defeat,
since you must reduce its power, grade by grade, until all nastiness
is gone.)
However, their task in defeating you is much easier; they merely have
to up their level of nastiness to the one above.
The philosophy of survival in the Time Vacuums is therefore quite
simple - if it moves shoot it - if it doesn't move shoot it anyway;
above all avoid contact with the nasties or anything they may send at
you for it's through these collisions that they will defeat you.
Here are your three principal foes:

Small but deadly, a single contact may be enough to bring you down.
They are escorted by their fawning cohorts (Slime Pawns) who both
protect their master and attack. These pawns will be reproduced should
you dispose of them and vary in number depending upon the nastiness of
their master. The status of the master is monitored on-screen by a bar
chart to the left of the Time Window.giphy (21)

They always occur in regimented ranks and will throw sludge as well as
hurling themselves at you. In their Time Windows you can only move
left and right, so you must wait until they attack and then respond
instantly, shooting their Sludge and then the Slugs themselves.
The progress of battle is monitored by a large "Status Slug" below the
Time Window. To the far right you have won; to the left, ignominious

The buzzing pests attack in swarms and have the same suicidal
tendencies as the Slime Pawns, but with more vigour, making them very
difficult adversaries. However, sometimes they swarm together,
seemingly uninterested in your presence - then is the time to move in
an annihilate them en-masse.
Status is monitored by a "Fly-in-the-Tube" to the right of the Time

These are your second line of defence against the "Nasties" roaming
the Time Vacuums. One of these defenders is dropped automatically each
time you score 1000 Toad points.
They delay the enemy who adhere to them for a certain time and are
immobilised. There are four time grades, denoting how long each
defender lasts: green 10 seconds, red 20 seconds, cyan 30 seconds and
white 60 seconds.
(N.B. The grade depends upon the difference between the Toad points
and the Slime points accumulated so far.)
The defender doesn't operate with every "Nasty", however; Slime
Masters and Sludge Slugs are too powerful, in fact Slime Masters eat
them as they pass over, releasing any pawns that may be attached!Screen Shot 2016-08-05 at 17.05.58

(A hitch-hiker's nightmare.)
This strange phenomenon of the Rygellian Time Void gives rise to the
travelling paradox - namely to travel along the Road gets you nowhere
but uses up time. The significance of the Road to your goal is that
crossing it (rather than going down it) you are transported from one
Time Vacuum to another, allowing you to "Leap Frog" to another Time
Node some distance away.
There are eight occurrences of the Road in the Time Void providing
links between four pairs of Nodes. When you start the game the linked
Nodes are coloured red in the Time Grid Window. Before you can cross
the Road and make use of the link you must find a key to the parked
car which will move away as you approach the Road, allowing you to
cross it.
(Like the pieces of the Tool Kit, the key to each of the links will be
found in the Time Vacuums; simply pass over to pick up.)
Next time you visit the Time Grid Window the key will be displayed on
the right and the Time Nodes which have an "Unlocked" link will have
changed colour from red to white. Once a link has been "Unlocked" by
finding the key it will remain so throughout the game even if you run
out of lives or Alpha-Pellets and are sent back to the start Node.

Dual points totals are constantly displayed:-
On the left are the points you have gained, Toad points. On the right
are the points you have lost, Slime points. The greater the difference
between them, the higher will be your grade of Timed Ultrasonic
Robotic Defender. (N.B. Points are only gained and lost in the Time
Vacuums between the Time Nodes.)
On each side of the Grid Map is status information. To the left are
displayed the eight pieces of the Tool Kit - the pieces so far
collected will be coloured, the ones not yet located will be black. On
the right are displayed the four keys from the Road to Nowhere and
Somewhere; again coloured if they've been found, black if not.
Below the keys, your remaining lives are shown (you begin with three)
and on-screen information includes the progress of the Sludge Saw on
its deathly descent! All elements of the game are colour coded to
indicate their status as described in each section, including bar
charts for the different "Nasties".$_3

You begin at the Time Node in the top right-hand corner of the grid,
and initially can only move down or to the left. Your ultimate
destination is the yellow Node in the bottom left-hand of the grid.
The minimum number of moves to traverse the Void is therefore 14,
though there is no restriction upon the number of times you may visit
a particular node.
Time is of the essence - you have 1 hour 30 minutes of Real Time to
complete your mission.
(N.B. The SPACE/BREAK key will pause the game and restart when pressed

1. The fire and movement control operating independently can prove an
   advantage. It means you can halt and fire by operating the fire
   control only and avoid collision with your foe (which as you know
   can prove fatal).
2. When battling with the Slime Master and his Pawns, it is most
   effective to outflank the Pawns defensive wall and shoot the Master
   himself (a bigger and slower moving target).
3. Clues to the locations of Tools - Each time you complete eight
   combat screens in succession (ie. eight without defeat) you will be
   shown the location of one of the Tools next time you return to the
   Grid Window. At the top the word 'Tool' will flash as will one of
   the Grid squares (it will be useful to make a note of this for
   future use).
4. Some Time Vacuums are easier to traverse than others and there are
   more, or less, difficult ways to achieve your objective. It would
   be useful to map the different paths to build on experience you
   have gained; the chances of succeeding at random are remote.
   GOOD SHOOTING!Screen Shot 2016-08-05 at 16.56.16


I remember this game being packaged with my Spectrum +3 on disk so as you could imagine it got quite a lot of play as I did not own many games and the fast loading time.

Surprisingly its actually a very entertaining game.

With its clear crisp graphics to its challenging gameplay.

The queen of the cosmic wartoads has been kidnapped by the Rygellian Slime Beasts, turned into a human and is being held captive beneath the Slime King’s Sludge Saw, which descends over the course of ninety minutes and will kill her if it is not stopped.

The player controls the Cosmic Wartoad as he attempts to rescue the queen. To achieve this he must travel across the Rygellian Timevoid, an 8×8 grid of “nodes”, by entering a node, successfully completing the minigame within, and then entering an adjacent node, all the while collecting the eight pieces of the Cosmic Toolkit that will shut down the Sludge Saw. Each node contains one of several repeating minigames, which typically involve the Cosmic Wartoad fighting one or more enemies on a pseudo-isometric screen.

I would recommend this to anyone who likes a challenge.

Check out the Simon Butler interview who come up with the concept.
