Chroma is an abstract puzzle game. A variety of colourful shapes
are arranged in a series of increasingly complex patterns, forming
fiendish traps that must be disarmed and mysterious puzzles that must
be manipulated in order to give up their subtle secrets. Initially
so straightforward that anyone can pick it up and begin to play, yet
gradually becoming difficult enough to tax even the brightest of minds.
