If you click on one of the 9 or 16 emos (emotionals) the color of the emos that are in the same row or column will change. The emo you clicked on does not change. Emos change from "happy" to "glad", from "glad" to "sad", from "sad" to "dying" and from "dying" to "happy" again. The game is solved when all emos are "happy". You can play this game by mouse or keys (arrow, space).

A good strategy is to increase the symmetry step by step. In this picture you should press the two green emos. After another two pressings the game is solved.
Warning: This emosaic game can cause a mania!
