I am so sorry for the mix up, ignore what I said previously! I've been playing a lot of games and got a bit confused as to what game this was. It was the sword slashing that threw me off.
He attacked in the last direction I was facing. Been as I was using the mouse to slash my sword, I was expecting him to slash towards the mouse, not the last direction pressed.
Also having the "E" button to use my item rather than the mouse click was a little odd to me.
