Casus is the story of a monster's escape from an alien planet. Little does he know that a prophecy fortold that he would come and destroy the land - hence why all the strange creatures keep trying to kill him.

While stationary, the monster can flip the world upside down and continue the journey on the platforms which were originally beneath him. There are a number of special platforms which don't flip with the rest of the world, and are useful for getting part certain obstacles. There are some clever ideas, although it would have been nice to get a few more checkpoints.
