Kurt Martin is standing in front of 180 fruit storage chambers. They belong to the vegetarian aliens who have invaded Earth. Kurt has got to clean them of every piece of fruit, so that the invaders run out of food.

Every solved room will gain him a key. With these keys he can unlock new areas of the game world.
Dexterity and logical thinking are needed to solve the rooms.

The game is about breaking colored fruit blocks. You can only break those which have your color. There are skulls which will kill you when they have the same color. By touching cauldrons the hero of the game can change his color.

Monsters guard the rooms. Sometimes you have to trick them to open passages which otherwise would be inaccessible.
Several items have to be used in a clever way. For example explosives can be used to blow up barricades.
