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.
