Coloropus is a young octopus who is trying to save his girlfriend, Pinky. In various levels, players will have to solve mainly colour-based puzzles: By eating coloured pearls, Coloropus can change his own colour and even create mixed tones, to be able to move accordingly coloured obstacles out of his way. The deeper they dive, the darker and easier it gets. Coloropus offers a wide range of challenging entertainment and tells its fascinating stories without using any words. All dialogues and game hints are presented as little comics in speech bubbles, not using any words.
