The game can be started by clicking the 'Start' button. Upon 'GAME OVER', the board can be reset by clicking the 'Reset' button, and a new game can be intialized by, again, clicking the 'Start' button. You can move left with the 'A' key, up with the 'W' key, right with the 'D' key, and down with the 'S' key. The objective is to consume as many of the pills as possible without colliding with the walls or with your own tail. Good luck!
