"Smileys" Game

Smileys is an interesting arcade game for attention and reaction speed. In front of you will open a playing field consisting of a certain number of cells. The cells will contain diamonds, smiling smileys and sad smileys. Your task is to make the sad smiley by clicking on them. The game is limited in time - on top of the playing field is a timer. You are allotted 30 seconds to search, but do not worry, because you can extend the time, if you find the cell alarm clock and click on it. Also, try to have time to collect all the crystals. As soon as there are no sad smiles left on the playing field, you can move on to the next level.
