Regarding controller support, I have used the 3D Control Pad successfully in terms of it being read, but the 3D stick does not work with VP - which is fine, I just love the feel of that controller! I also used the Flight Stick and positioned it for left handed use to feel more comfortable, and that has actually become my preferred way to experience Vigilant Paradise!
The game plays great overall on my Satiator. Keep up the great work!
