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.

XOR was published by Logotron Longman in 1987. It is a puzzle game similar to Chroma but with surreal elements such as chickens, fish, bombs and dolls. This package provides the Chroma themes files to have Chroma SDL implementation look like the original XOR.

It should be noted that unlike Chroma, XOR is not opensource, thus this package will never go in an OSS repository. However the authors of XOR have never complained eventhrough there are quite a lot of reimplementations of XOR hanging around the Internet.
