As mentioned, being able to use a controller is a nice addition. But..
Since the game doesn't really have much gamplay activities and is mostly chatting or roleplaying that requires a keyboard to write anyway, I think this looses some purpose.
If there was actual missions, rewards, platforming and other fun stuffz using a gamepad would seem more at home, but right now it really doesn't if you ask me.
I don't mind the idea, I just don't see much use of it xD
