I just wanted to say I really appreciate the option to use the mouse only to play this game. I had never expected this to be included. This is so much better for me than using a joystick or the keyboard.
Also, I think it works pretty well! I read some people found it awkward... and of course it won't be the same as point & click (maybe they're comparing it to that?), but for what it is... it works very well. I does not stand in the way of me enjoying the game, I got used to it in minutes and now I don't even think about it anymore.
