I can't find mouse controls in the in-game settings. I tried both normal window and fullscreen. I use both Google Chrome [and yes, i know that mouse controls don't work with this browser] and Opera but neither of them display the mouse control option. NOTE: I wasn't active both in-game and forum during the time mouse controls was released into the official game, and so I just realised it now.
