The Three-Player Crazy Crystals levels require teamwork to complete all of them. The blue player uses the arrow keys to move, the green player uses W for up, A for left, S for down and D for right and the pink player uses I for up, J for left, K for down and L for right. As they are designed for several players on the same machine, they do not give achievements.
