Mirror is a puzzle game involving placing reflected dots. The screen is a simple fractal background with a line representing a mirror on it, and a shadowy node. Once you guess where the node would reflect to, you place your marker and the game tells you how close you got. There are 81 levels, each more difficult than the last. The later levels involve up to 9 mirrors, with 9 different markers to be placed. Overall, the game offers a quiet, peaceful puzzle to crack.
