Gamut is a fast-paced puzzle game. Players must navigate Roy through a 2D maze of interactive objects to advance through a series of levels. Players can open up new paths for Roy to travel by changing the color of the world, which phases all objects of that color out of existence. In addition, there are enemies out to change Roy's color, which will cause him to pass through any object of that color. Players must determine whether to use an enemy or avoid it in order to navigate through to safety.
