Chroma is an abstract puzzle game in which a variety of colorful 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, it is so straightforward that anyone can pick it up and begin to play, yet it gradually becomes difficult enough to tax even the brightest of minds. It features twenty-one levels, ranging from beginner to expert; infinite undo and redo capability, as well as replaying of solutions; a choice of smooth graphics or a minimal, text based version; and a level editor to allow you to design your own puzzles.
Hunt-ng is a fork of Hunt, a multi-player search-and-destroy game that takes place in a maze. It aims to improve playability while preserving the charm of the original.
