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.

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.

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

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.

Platforms that move in a constant loop

Pivot Platform

See-saw type platforms with a pivot

20

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