Universe

T

he Goo-Fu universe has strange and varied landscapes and creatures. There
are many different species of intelligent to semi-intelligent creatures on
Coop’s planet. The part where Coop’s people live is a Goo-swamp, and the
creatures are made mainly of goo, like humans are made mainly of water.
However, the geography of the planet changes drastically and also includes molten
lava-filled landscapes, tropical forests, icy mountains and deserts

2

Premise and characters

T

his game is set in planet Sludge, which is inhabited by various creatures,
including an intelligent race of cute little beings called Goo-Balls.
The protagonist, Coop, is a regular teenage Goo-Ball that loses his family
to an enslavement raid by the Evil Master. Coop manages to escape to the
most isolated and desolate corner of his planet where, on the verge of death, he is
rescued by an old, eccentric Goo-Ball who sympathizes with his plight and teaches
him the secret art of Goo-Fu and the Three Form Technique, so that Coop can
avenge his family and save the Goo-Balls.

3

Visual Style

G

oo-Fu is in 3D and played with the camera locked in side-view, like the
game Trine. The dark storyline, where Coop’s family is dead and his
people are in jeopardy, along with the destruction of the land are
contrasted by colourful, humorous characters.

dedicated to that form.

17

Enemies

E

nemies in Goo Fu follow paths, have timed attacks (e.g. swinging
pendulum), aimed attacks, looped or random attacks. Some come after
the player and others just patrol their area like the turtles in Mario.

Plants
Sucker Plants

Plants that are like vacuum cleaners, sucking things
that come too close and then grinding them with their
multi-layered, oppositely spinning teeth. (If they suck
up a rock, etc, they get jammed)

Random Pea Shooter

A plant that slowly inflates and then implodes. The
built up air, when released, shoots small seeds in
random directions.

Aimed Pea Shooter

A plant that aims at the player and shoots seeds (bullets)
at him. It has a part that inflates and deflates like a
balloon to shoot the seeds.

Eater Plant

A plant that pops out and swallows things that come
close.

18

Animals
Camo

A creature that camouflages itself by digging into the
ground and then jumps up to attack.

Spiky blow random

A plant that inflates by taking in air, and then releases, flying
around like a balloon, causing damage with it’s spikes.

Spiky blow aimed

A small, deflated-balloon-like creature that
inflates itself when it senses danger aims at the
intruder and then propels itself spike-first at it.

Fireflies
These files are at certain places in the game moving about along
certain paths. They are constantly on fire so they can damage the
player, especially in inflated form.

19

Level Elements
Platforms
Platforms are of various types in this game, including ground, trees, rocks, etc.
Plants

Plant-structures that can be used as platforms

Flexi-branches

Flexible branches that can be used as jump-boards

Grabbing Platforms

These platforms are on the top side of the scenario so Coop has to grab them with
his limbs to cross them

Anti-Grab Platforms

These platforms cannot be grabbed by the player
Poles

Can be used to do 360 ° swings
Moving Platform

Platforms that move in a constant loop

Pivot Platform

See-saw type platforms with a pivot

Players can achieve much higher jumps with these

20

Obstacles/Hazards
Elements that can harm the player or stop him from progressing.
Lava

Will kill the players that fall into it, can also spout lava balls
Acid Pool

save himself till he completely drowns in the pool
Rocks

These help contribute to puzzle elements and can be used by the player to kill
enemies
Thorns

Thorns are placed in the middle of the path. Inflated form is especially vulnerable
to these.
Conveyor belts

Platforms that act like conveyor belts, pulling the players in a certain direction if
they are standing on them
Blocking Walls and Planks

ball form to help the player to pass through them
