Been looking forward to this game for quite some time now, even though most people I have spoken to have not even heard of it. Unfortunately the demo felt a little... meh.
As Sazar has said, the controls are off. I personally felt the overall animation was weird, though that could just be me, it also seemed though the enemies were rather stupid.
Hopefully any issues raised by releasing the demo may be fixed once, or even shortly after, the full game is released.
