I enjoyed playing Cranky Cat. I could see a potential for a two player mode. One player rotates the central black orb while another player launches the orb from anywhere the second player pleases. You need either a keyboard for the second player and the mouse for the first player. The Mobile version might need two phones for mobile two player mode. Possibly the only way to unlock two player is by paying for it. Will there be a level designer for this game? Even without my suggestions Cranky Cat is already very addicting.
