To give you a better explanation, this game requires an absolutely absurd level of speed and precision with your inputs to be able to move effectively. When you start playing, even as a skilled PC gamer with a mouse and keyboard, it'll be hard to even move around. A controller just doesn't provide the level of precision at speed you'd need to be able to enjoy the game. I don't know if there are any plans to make it controller compatible or if it's possible, but I just don't think this is the kind of game that would be very fun on controller. It's like playing a driving game on mouse and keyboard. It can be done, but it's just not as enjoyable as other input methods.
