The game is played using W,A,S,D or the arrow keys with these keys you control the direction of where your player is going, if you end up hitting the borders of the wall u will lose the game and the goal is to survive and eat as many red players as you can. Eating the red player will create a chain which keeps growing as you keep eating the red player, While doing all this u will still have to avoid hitting the wall no matter what, try aiming for the highest score possible.
